Of course I’m joking. This tabby cat is not a criminal. But he has been filmed and in human parlance he is engaging in an act of theft: criminal behaviour. What is charming is that he takes the plush toy (a tiger?) to a quiet, secret spot where no one can see him and he plays with it.
PS-I have made a presumption which could well be incorrect. I have presumed that the plush toy does not belong to this cat. It may belong to him. But I suspect that it belongs to a child and that this cat is part of a family of which the child is also a part.
