Yes, they will kill mice. But, as another said, they will leave the little dead critter lying around in the house somewhere! You can then pick it up with a paper towel, or something, and put it outside. Good luck.
If the cat has enough food it may not hunt mice, or only hunt as a hobby. And then it brings the dead mice into the house. Better get some mouse traps - at least you dont have to buy food them or take them to a vet.
Female kittens grow up to be the best mousers. Make sure you keep vaccinations up to date, rabies, etc. and you should not have any problems. My cat chases mice up from the woods and she'll kill them and eat them. About once every three months, I give her medicine I bought at Tractor Supply for tape worms. Not saying she has them, but if they eat rodents, it's better to treat them. It won't hurt them.
It depends how many mice that you have before you get the cat. If you are using the cat as a preemptive strike, the cat might keep the rodent problem in check. However, like some of the earlier suggestions state, the cat may not go after mice/rats, and if they do they will only get one or two a day.
I had an exterior rat infestation 2 years ago. There is a better solution:
Use Cayenne pepper. You sprinkle it next to walls and any where the mice are. They use their whiskers to "feel" their way around until they are comfortable to be in the opening of a room. I use a 16oz bag in my backyard and got rid of the rats over night (along with the other critters that were coming into my yard).
Cayenne pepper will not harm the animals or birds, The critters are using there sense of smell to find food and like you and I, the pepper is an irritant to our senses and they will avoid it. I use it around my bird feeders. If it rains and you still have a problem, reapply it, that simple.
Cats, due to their curiosity will rid your house of mice, crickets, flys, spiders, and most anything that is smaller than them and moves. They may not eat the carcasses of everything, but they will continue to play with them until they cease moving.
Depends...'cuz some cats are afraid of mice. But if it DOES,it expects to be feeding you if it brings it to you. So,smile and tell it,"Good kitty!" (unless it was your pet mouse :P ) and dispose of the body and don't let your cat know. It might get efencive...watch you back...
ya.my cats do that all the time. sometimes they will bring the dead mice into the house but take it as a compliment. they think they are feeding the humans, or maybe they are just trying to be nice and give them a present.
Most farms have so called wild cat's (house cats they don't feed and stay out side) They do a very good job of rodent control. If your cat stays in your house and you feed him, he'll learn to make friends with the mice. Buy a mouse trap then you know where the dead mice are.
