I have 2 black cats, Pickle and Jack. Pickle is an old lady (12) and a bit plump and cuddly, and occasionally a bit grumpy. She can't be bothered to go hunting. Jack (1) is a bit of a naughty boy! He steals any food available, but worst of all, he is a very good hunter. It's getting to the stage where I am not looking forward to coming downstairs in the morning, because I don't know what surprises will await us. I'm thinking we might need to get him a collar with a bell. Has anyone any tips?
