its a weird thing when your cat starts eating food off of the floor. my cat does exactly that. he is very strange indeed. ever since i brought him home from the vet as a kitten, he has be strange ever since. He decided to climb up the chimney once and when he came down, he ran around the house. He got into a skunk fight later and was a smelly furball. If its one word that I can use to describe him, it would be stupid.
