Does your outdoor cat regularly deposit small, dead rodents on your doorstep? Or does your indoor cat seem to take pride in hunting down large, ugly bugs in your apartment and leaving them at your feet? Believe it or not, your cat is not bringing you a gift, 288 according to animal behaviorists. “Your cat is actually bringing you a mouse to teach you to hunt and kill it,” explains Katherine A. Houpt, VMD, the former James Law Professor of Animal Behavior at Cornell Universitys College of Veterinary Medicine. “Its the same thing the mother cat does for her kittens.” Cats are born with a chasing and hunting instinct, but not necessarily the skills to go along with it. The mother cat teaches her kittens to kill and eat prey. (Indoor cats may chase and kill mice, but they will rarely eat them.) Mother Knows Best. The lessons start when the kittens are about four weeks old. The mother cat begins by bringing home dead mice or other prey and eating them in front of the kittens. The kittens soon catch on and join in. Next, the mother cat brings home dead mice and the kittens eat on their own. The next stage is a turning point. The mother brings back live but wounded mice. The kittens play with the slow-moving mice, eventually killing and eating them. Gradually, the kittens become more coordinated at tracking movements and skillful at pouncing on the prey. Pouncing helps the kittens learn to gauge distance. As the kittens become more experienced, they begin to hunt with their mother and kill mice on their own. By four or five months of age, kittens are sufficient mouse catchers. But theres something to be said for more experience. “Research shows that compared to older cats, six- to eight-month-old cats catch fewer mammals,” says Dr. Houpt. The whole process of mothers teaching their kittens can be compared to the way in which your cat may try to teach you. First, cats usually bring dead mice to their human companions. Then they bring over live mice, expecting their human companions to get the idea very quickly. Experts note that spayed females are more likely than their male counterparts to catch mice for their humans. How do we know the mouse really isnt a gift for us instead of training material? “There are very few instances in nature where animals bring gifts to each other,” says Dr. Houpt. Eating and survival are at the root of most behaviors that one animal exhibits toward another. And your cat considers you a kindred cat of sorts. So what do you do if your cat drops a mouse at your feet? If you praise your cat, youre encouraging her to bring you more mice,” says Dr. Houpt. “Youre reinforcing a behavior you probably dont want your cat to repeat.” Therefore, dont praise – but dont scold your cat, either. After all, your cat is following her predatory instincts that are necessary for survival. Your best bet is to “act as neutral as possible and quickly get rid of the mouse.” Dont make a big fuss over the mouse – either way – because your cat will interpret excitement as a reason to keep on catching and bringing you mice. A dead mouse is difficult enough to deal with for most people, but a live mouse is another story. “Its a problem,” says Dr. Houpt. “Theres no easy answer. If you distract your cat somehow, she will usually drop the mouse. If the mouse is unhurt and you live in a rural area, you can release the mouse outside.” Putting the mouse outside on the streets of an urban environment, however, isnt the best idea for the mouse. “If possible, take the mouse to your veterinarian or the animal shelter, where the experts will decide on the best course of action,” says Dr. Houpt. “But be very careful and try not to touch mice with your hands. They can nip you and can carry diseases such as Lyme disease or the Hanta virus,” a rare, but very dangerous illness transmitted to humans by rodents. Experts understand why cats hunt, kill and bring mice to their human companions. But the big question is: why do cats torture their prey? “We really dont have a good explanation for that,” says Dr. Houpt. “Its possible that this behavior represents pent-up aggression, especially in indoor cats.” If your cat doesnt have enough predatory adventure, she may be bored. So when she does catch a mouse, she wants to prolong the fun.
