Giant Rat Found Inside Of A Foot Locker Store

Yesterday someone Tweeted this photo of a giant monster rat, supposedly discovered at a Foot Locker in the Bronx. You might recognize this guy, as he bears a striking resemblance to the 3-foot-long beast that was stabbed with a pitchfork in Brooklyn last year. That one was believed to be a Gambian pouched rat, and may have been someone's escaped pet. However, it wasn't the first one spotted in that area, and locals believed they were multiplying faster than Gremlins taking a bath.

With this spotting in the Bronx, we think it's safe to say this superbreed of mutant rat is priming for a takeover of the five boroughs (everyone grab some Mountain Dew). Was there anything in that Mayan prophecy about rodents?

Pennsylvania’s Purple Squirrel A Rainbow-Colored Riddle

A bright purple squirrel trapped by a Pennsylvania couple has experts offering all sorts of theories -- but no concrete answers.

Percy and Connie Emert from Jersey Shore, Pa., trapped the brightly colored creature while trying to keep the birds safe in their backyard feeder, reported Accuweather.com. They told the weather service they had no explanation for the rodent’s deep purple color.

"We have no idea whatsoever. It's really purple. People think we dyed it, but honestly, we just found it and it was purple," the Emerts told Accuweather.

Experts queried by Accuweather had several theories for the unusual look, but no hard answers. Indeed, Krish Pillai, a professor at Lock Haven University of Pennsylvania, told Accuweather he thought the coloring was dangerous for the animal.

I’ve got to think one of the suggestions might be it fell in a Porta John that had blue coloration. - Henry Kacprzyk, Pittsburgh Zoo curator

"This is not good at all. That color looks very much like Tyrian purple. It is a natural organobromide compound seen in molluscs and rarely found in land animals. The squirrel (possibly) has too much bromide in its system," he said.

Some AccuWeather.com meteorologists had their own theories. Expert Senior Meteorologist Henry Margusity thought it was merely an accident.

"The squirrel could have been looking for somewhere warm and fallen into a port-a-potty or something similar," he said,

Henry Kacprzyk, a curator at the Pittsburgh Zoo, said Thursday he thought it looked like a gray squirrel tinged in purple, after looking at a picture of the critter on an iPhone.

He knows of albino squirrels. Black squirrels. Gray squirrels. Reddish squirrels.

“But the purple coloration, from the purple I saw … it looked to me like this animal had come in contact with something with its fur and dyed its fur,” Kacprzyk said. The squirrel could have come in contact with a pokeberry patch, but pokeberries aren’t in season.

And strange as it sounds, he thought Margusity’s toilet theory might hold water.

“I’ve got to think one of the suggestions might be it fell in a Porta John that had blue coloration,” he said with a chuckle. “I have no idea why … but I don’t think it was born that way.”

When asked about the suggestions by some people in online forums of the potential impact of fracking fluid, Kacprzyk said the composition of such fluids in Pennsylvania wasn’t known. “My guess there is if you don’t know something, is that there’s no scientific proof to that. … I would find it amazing that it had that kind of effect,” he said.

In general, purple is an unusual color for mammals, let alone squirrels.

“There are definitely birds that have coloration like this … but not mammals,” he said. “Mammals don’t normally uptake color, ingest something it goes through and (then) it comes out through their fur.”

It's true: Rodents Will Chew on Your Car's Wires

Chew on this. Your warm car engine may also have a warm rodent nibbling on the wires.

"I had to replace some wiring due to rabbits chewing," a Times-Call reader said on Facebook.

"There is apparently an epidemic with squirrels and rabbits chewing electrical wiring and so forth under the hoods of cars," another called into the TC-Line on Jan. 4.

Not quite an epidemic, local mechanics say. But far from uncommon.

"It is a fact," said Scott Nichol of Hitek Professional Automobile Repair, who says he gets six or seven cases of rodent damage a year. "It is a cold, hard, nasty fact. Summertime, wintertime, fall, it doesn't matter. ... The more squirrels you have in an area, the more you see things like this."

Travis Paswaters of Hayes Automotive said he tends to see it a little more in the winter. Squirrels and mice aren't specifically looking for your wires, he said, they're looking for a place to nest -- and in the winter, a recently parked car that sits for a while provides a perfect home.

"We pull nests out of air boxes and intake valleys all the time," Paswaters said. "And if they get down and chew something you can't find, you can get a pretty nasty gremlin. One, I remember, chewed the ignition coil wires. The car would run rough because one of the cylinders wasn't firing."

And sometimes it can add up to more than just a rough ride. Last May, a car caught fire and burned; police later determined it was because of a squirrel nest in the engine.

"If they chew up the wiring, you can have a car-becue," Nichol said.

So what can a driver do?

First, keep the car in a garage if you can. You can't close off all the entryways a rodent would use -- they're openings that the car needs -- but putting the vehicle inside makes it less likely that squirrels will pay a visit. Mice may still be a risk, though, Nichol said, especially outside of town.

Second, open up the hood and check the engine regularly, Paswaters said. If you find twigs, bits of leaves or other nest-building material, you might just have a visitor. Having the oil changed regularly will help, too, he said, since the mechanic will be alert to signs of trouble.

One common home remedy is to use mothballs or paint the wires with Tabasco sauce to discourage chewing. That can work, Paswaters said, but it can also have unpleasant consequences, since the fresh air intake is near the core of the engine.

"It'll make the HVAC unpleasant," he said, referring to the passenger heating and cooling system. "You'll be getting that smell yourself."

Nichol advised not to try putting poison down near the car; the risk of a pet consuming it by mistake isn't worth it, he said. The best thing you can do, he said, is not to let the car sit.

"Don't keep it parked for weeks on end," he said. "Make sure the car moves."

Squirrel Takes Out Power for Thousands

More than 4,000 Ohio Edison customers lost power for about three hours after a squirrel stepped on a substation bus and blew a fuse for a transformer covering the west side of Lorain and the east side of Vermillion.

According to FirstEnergy spokesman Todd Meyer, 4,123 customers lost power at around 11:17 a.m. when the rodent snooped too close to the electrical equipment.

“Whenever anything comes in contact with high voltage equipment, then something usually goes wrong,” he said.

The outage disabled traffic lights on Baumhart Road. A temporary stop sign was put in places for travelers turning on to Baumhart from West Erie Avenue.

More than half of the customers had power back 1:30 with the remaining customers powered on by 2:30 p.m., Meyer said.

The outage did not affect Mercy Regional Medical Center, he said.

Allston Man Charged With Firing Rifle at Rats in Apartment Hallway

A 57-year-old Allston man faced charges today for allegedly firing an unlicensed rifle at rats in the halls of his Franklin Street apartment building because of frustration over an infestation of the vermin, according to the Suffolk County District Attorney's office.

William McAbee was arraigned in Brighton District Court for unlawful possession of a firearm, unlawful possession of ammunition, and unlawfully discharging a firearm within 500 feet of a dwelling, prosecutors said. A not guilty plea was automatically entered on his behalf, and Judge Kenneth V. Desmond set his bail at $2,500, district attorney spokesman Jake Wark said.

Rats: Holiday Spirit, in Rodent Form

During the holidays, if kids become brats, you can shout with a straight face, “Start acting like rats!’’ According to a study in the journal Science, University of Chicago researchers discovered that lab rats can show empathy — a quality not previously demonstrated in rodents — at levels that are rare even in primates.

Free rats sensed distress in caged rats and worked tirelessly to free them. When chocolate chips were added to the experiment, the free rat did not selfishly gobble them up and let the caged rat languish. It still freed the other rat and shared the sweets. Researchers hope their observations will inform studies of human empathy. Despite the rat’s image as the first creature to abandon a sinking ship, the new finding may inspire a rising tide of concern for one’s fellow beings, especially during the holidays. If even rats put others first, surely humans can, too.

Research Uncovers Empathy in Rats

As charges of greed and self-interest fly in these hyper-partisan political times, humans might do well to look to rats for lessons in kindness and caring.

A University of Chicago experiment to determine how much empathy rats have for each other had some surprising results, which were published Friday in the research journal Science.

In laboratory studies, a rat was restrained in a small cage that could be opened only from the outside. A second rat, seeing the predicament of the trapped rat, immediately began tirelessly trying to find a way to free his fellow rat.

Eventually, the second rat taught itself to open the cage door, freeing the restrained rat, leading to what strongly resembled a triumphal celebration between the two. Even when faced with an alternative choice of chocolate chips, the free rat would not be deterred from helping its caged fellow rat.

As simple as it sounds, the experiment is being hailed as a new paradigm that will help scientists trace the development of emotion in mammals back through the evolutionary tree.

Previously, scientists thought that empathy and pro-social behavior to help others were unique to humans, said Jeffrey Mogil, a researcher at McGill University in Canada who has done similar studies on mice.

“This study shows the roots of human empathy didn’t just appear but evolved,” said Mogil, who was not connected with the University of Chicago study. “It is very impressive, showing really robust and conclusive evidence that rats show pro-social (helping) behavior. You can argue why the rats are doing it, but you can’t argue anymore that the rats are doing it.”

The experiment is the work of University of Chicago doctoral student Inbal Ben-Ami Bartal; her adviser, Jean Decety, a professor of psychology and psychiatry who studies human empathy; and Peggy Mason, a neurobiology professor who studies pain modulation and relief.

Decety said it has been proved in past studies that rats also experience a primitive form of empathy called emotional contagion — the sort of thing where if one baby in a group of babies begins to cry, they all break out in tears.

“Ben-Ami came to my lab to do her Ph.D. with an idea of using an animal model to study higher forms of empathy,” said Decety, who enlisted Mason for a study that wound up taking three years.

The team first paired rats of the same gender for three weeks.

Then they placed one of the pair in a small, Plexiglas restraint cage, locked by a door that could only be opened from the outside. The cage was placed in a larger enclosure where the rat’s partner roamed free.

By means the researchers aren’t sure of, the caged rat seemed to communicate its distress to the freed rat, and the freed rat sprang into action.

“The free rat jumps on the restraining cage immediately, pushing it, biting at it, touching its nose and whiskers through the openings in the restraining cage with those of the trapped rat,” Mason said. “Clearly it wants to help out the trapped rat.”

After about six days, the free rat would accidentally open the door and from then on quickly learned how to deliberately open it, and then excitedly interact with its now-free partner as they raced around the enclosure.

“I can’t say that they are celebrating,” said Mason. “But sure looks like a celebration.”

Because rats love chocolate, in some experiments the scientists placed two restraint cages in an enclosure with a rat that already knew how to open the cage door. One cage contained a rat, the other five chocolate chips.

“We wanted to ask how much the free rat valued being able to liberate the caged rat,” Mason said. “They like their chocolate chips, but the free rat would open both cages in no particular order.

“The free (rat) could have done all manner of things to monopolize the chocolate chips, but on average it always left one and a half chocolate chips for the liberated rat. That’s impressive — a hard thing for primates to do — showing it puts equal value on chocolate and freeing its partner.”

Eventually rats that did not know each other were used, and the free rat still worked hard to liberate the stranger from the cage.

Boston Cop Mailed Dead Rats as Payback in Sex Ring

A Boston transit police officer has been suspended after he was caught mailing dead rats.

Why was he mailing dead rats?

According to CBS Boston, the officer was sending a message to a man who failed to pay the cop's girlfriend or another prostitute for sex.

Not your run-of-the-mill dead rats in the mail story.

MBTA Police Officer Greg Thorpe was caught mailing dead rats to a Hyde Park man, from a UPS store in South Boston about ten days ago. Sources tell the CBS Boston that Thorpe was caught on video by security cameras in a UPS customer service center, mailing two packages. At one point he reportedly looks at the security camera and smiles.

Sources say officer Thorpe's girlfriend offered her "services" on Craigslist and that the uniformed officer would drive her and her friends to appointments in his marked MBTA cruiser during his midnight shift, offering protection.

Sources say one man never paid one of the girls and so Thorpe mailed him the rats.

The MBTA police released a statement, saying, "Greg Thorpe has been placed on administrative leave pending the results of an internal investigation."

Sources tell CBS Boston officer Thorpe may at some point face charges from Boston police for intimidating a witness and animal cruelty.

Feds Remove Food from Rodent-Infested Warehouse

Federal authorities seized food from a Streamwood warehouse Monday after investigators found a "widespread and active rodent infestation" inside the building, according to the U.S. attorney's office.

Criminal investigators with the Food and Drug Administration also executed a search warrant Monday at the Chetak Chicago LLC facility, signaling a criminal probe of the conditions at the suburban location.

The developments come after the FDA found 25 live and 12 dead rodents at the warehouse between Aug. 15 and Sept. 1, authorities said. FDA investigators also spotted birds inside the 108,000-square-foot building as well as gnawed and urine-stained food packages, according to the U.S. attorney's office. Investigators also found rodents' nesting materials inside the building. Gaps in the doors and the foundation allowed animals to enter, prosecutors said.

FDA investigators returned to the building twice in late September, but the problems had not been fixed, authorities said.

The discoveries prompted federal prosecutors to file a lawsuit alleging that all food inside the building can be seized unless stored in a freezer or in glass or metal containers. A federal judge signed a warrant allowing deputy U.S. marshals to seize the food.

The facility, located at 1111 E. Lake St. in the northwest suburb, stores food including rice, flour, shelled peanuts, cookies, dried coconut and spices, according to the U.S. attorney's office. Chetak receives the food from India and throughout the United States and sells it to restaurants and retailers in about 20 states and Canada, officials said.

No food has been shipped from the building since Aug. 17, when the Illinois Department of Public Health imposed an embargo on the facility, officials said.

The U.S. attorney's office said "there are no known immediate public health risks posed by the seized food" and that no illnesses have been traced to the food.

Officials with Chetak could not be reached for comment.

African Rat Protects Itself with Poison

Researchers, including U.S. conservationists, say they've discovered the first known mammal to use plant poison to defend itself.

A predator trying to make a meal of the African crested rat is in for a surprise, the researchers said, because the rats apply a poisonous plant toxin to sponge-like hairs on its flanks.

"The African crested rat is a fascinating example of how a species can evolve a unique set of defenses in response to pressure from predators," said study co-author Tim O'Brien of the Wildlife Conservation Society in a WCS release Tuesday.

"The animal and its acquired toxicity is unique among placental mammals."

The researchers discovered the rat gets its poison from the bark of the Acokanthera tree, the same source used by East African hunters for poison arrows, by chewing the bark and applying its saliva to its flanks.

Scientists have long suspected the African crested rat is poisonous, with many accounts of dogs becoming ill or dying after encounters with the rodents.

But instead of producing poison itself, as the duck-billed platypus does, the African crested rat takes its toxin, called ouabain, from the external source, the tree.

A remaining mystery, researchers say, is how the animal uses the poison without succumbing to it.
