So your cat is crying to come in and you open the door for it, whats it do? its sits there or stands there looking at you and it waits (somehow it knows) how long you will stand there and then right when you go to shut the door it runs by you (just fast enough so that you cant give it a tap on the butt for making you wait)
Ok so you go to the kitchen and open a can of tuna or whatever (you know animals in this country eat better than the people do in a lot of countries) Anyway you put the cat food on a plate and place it before the cat and what does it do. It lifts up it leg and starts licking it's butt first.
Well i have the answer for this folks, Butt flavored cat food, its what they want
