Well, I have a strang question. I have 2 cats, and they both go BONKERS over photographs. They start growling and licking the tops of them. Is this normal? Is there something on the picture that they crave. I have had hundreds of photos eaten and distroyed by them. Also, the male cat will lay on the floor next to a plastic grocery bag and lick it until he puts a hole in it. Is there some difficiency in his diet that causes this? Is this related to the photograph thing? Please let me know, hendu213@yahoo.com
