I wish there were a way to discourage this, but you can no more discourage her hunting and bringing home the catch than you can discourage her from being a cat.
Keepers of outdoor cats know one thing, kitty loves to bring in dead little animals. This is one of the more distressing things in kitty's bag of tricks.
So why does kitty do this?
Cats are predators by nature and are amongst the best hunters in nature. It is their hunting skills, especially their ability to kill mice, that brought cats & people together. Cats were domesticated by farmers thousands of years ago to help them protect their crops from rodents and other animals. This is augmented by the fact that cats hunt even when they are full. Because kitty views people as either parents or children that need help, he feels compelled to bring us food. In essence kitty is trying to do his "fair share" for the family. This is coupled with kitty's desire to save his 'earnings' makes it more of a problem. Cats have a natural desire to store food for more scarce times. An example in nature is that of the leopard placing a catch in a tree. To our cats, our homes are those trees and are thus the place where the catch is brought and stored.
Other than keeping kitty an indoor cat, there is little you can do. Continue disposing of the catch as you are doing (please rubber gloves while disposing of the catch and wash thoroughly after handling these animals). Consider moving the feeding tray to another area so that the kitchen does not become the central depository. Also, be aware that continued exposure to wilds of the outdoors puts your kitty at greater risk of injury and disease. - Simba
Hunting Breeds in Cats
I have been having some mouse problems and am considering getting
The spaying/neutering does not affect a cat's natural instinct to hunt and kill prey. Cats are prolific hunters and a feline in your home will reduce the incidents of mice. So what breed to get?
Aside from the Norwegian Forest Cat(a large, furry creature), the American and British Shorthair cats are the best hunter cats out there. The British Shorthairs are healthy felines that have a calm, loyal and playful personality. They are thick-legged, heavyweight cats that can hunt very well. The American Shorthair is a descendent of the British version the pilgrims brought over in their voyage to the New World. The American version is natural hunters and cheerful lap cats. They have an even-temper and can be independent. Their natural agility makes them keen hunters. American shorthairs have a short, thick coat with a coarse texture. The most popular pattern is the tabby, with clear, dark stripes on a lighter background (this helps camouflage kitty). There are some things you need to be aware of.
