If I lived in town I would keep my cat indoors. However, I live on a farm so I have three cats outside. All are neutered. Two are pretty worthless as far as hunting but one is a superb mouser. She occasionally gets a bird but very rarely. She always leaves her kills where we can see them. Actually a Jack Russell terrier is the very best varmint killer there is. Relentless killers of vermin. A Jack on a mission is a sight to behold.
i adopted a beautiful short haired tiger that wandered up to me one day...inm the last year, i converted him to an indoors cat...but before that, man, he was a master killer. Once saw him trotting up the street with the biggest flapping crow in his mouth..i swear that bird was almost as big as him...but yea..he didnt always kill his prey. but rabbits..rats...mice...he was an ace at it. i converted now after he got a lil sick one day. Hes adjusted beautifully, and hes a good looking cat.
