My two year tomcat (neutered) has recently killed 3 bluetits that nest in the eaves of our house. He has killed mice and birds in the past. He always wears a collar with a big noisy bell. What else can I do to stop him killing and being his victims home? Thank you.
ignore him, as BOO says, he is bringing you presents - my cat only ever used to go catch a bird after we had been holiday and he had been in kennels, as if to say thanks for bringing me home! It wasweird, within an hour of being back home he would appear at the back door with a mouthful of something, but never bothered the rest of the year.
I am afraid there is nothing you can do to stop a cats natural instinct to kill and hunt for prey. No matter how big/noisey the bell, fact of the matter is cats are very wise creatures and will learn very effectivly to stalk mice and birds so the bell on their collar wont 'tinkle' !
He is giving you presents to say he loves you. Cats will be cats. Is he climbing up under the eaves? If he is, you could put something in his way to deter him.
Sadly, as the others have said, this is what cats do and it's never pleasant. There are a lot of very young birds out there and they are fairly easy pickings at the moment. Your cat is just bringing food home for you so he's not doing wrong in his eyes at least.
