My 13 lb cat, Paul...will not come unless you say his name or say "FAT!". Then he comes. But his thing is, he thinks he is a dog. He eats their food, he drinks their water, and he sleeps with them. When I take them out to potty, they get a milkbone when they come in.....Paul has to have his little piece of milkbone too, or he will drive you nuts till he gets it. He also drools when you pet him, which is really gross
