The predator instinct is inborn, but kittens also learn hunting by watching their
mothers. So how old is a cat when he can do his own killing? Roughly two months, by which time most kittens can catch and kill a mouse. Here’s a curious thing: a minority of cats seem to be afraid to hunt, and those cats are also fearful of humans. In short, a cat who doesn’t like to hunt makes a poor pet. Cat owners who are angry at their
pet for bringing home birds or mice ought to consider that a good hunter is also a warmer companion.
