CATS have an in-built instinct to chase things that move, and if your kitty is a hunter, there is not much you can do about it. You’ve as much chance of changing your cat’s nature as you have changing your eye colour.
However, you can curtail your pet’s attempts to massacre local wildlife.
First, buy an elasticised collar with a bell so that prey can hear your pet coming.
Note that the collar must be elasticised and be loose-fitting so that if your kitty gets stuck on a branch or fence, he or she can slip the collar instead of strangling to death.
Second, keep your pet in at night. Cats hunt mostly in the dark, and birds and bats tend to be most active just before dawn so by keeping your pet in at night, you shorten their hunting time.
These tips should work to keep fatalities at a minimum; however, do remember that if your cat kills, it does so because it’s natural. So don’t scold or be angry because your pet won’t understand your reaction. Your pet is part of the natural world and is doing a natural thing.
Finally, if your kitty does get lucky, he or she may pick up mites, worms and other health problems from contact and kill. Prevent health problems by making sure your pet is vaccinated and dewormed on an appropriate schedule. Cats differ, so talk to your vet about this.
