We have 2 cats, one is lazy, fat and sleepy and loves to be inside asleep. The other is a lean, mean murdering machine that spends his days hunting. There is not a rodent, bird or other furry thing safe anywhere near us. His recent kills include 2 grey squirrels (which he appeared to find particularly tasty) Pigeons and starlings appear to be a particular delicacy also. There is hardly a day goes by when Im not disposing of the carcass of some furry or feathered departed creature. I could understand it if he wasnt well fed but this cat eats like a navvy, guess its just instinct! We dont have much of a bird s@@t problem
