Oh, good lord. I saw a case on "Animal Precinct" on Animal Planet of a woman with several cats who was feeding them a vegetarian diet. They were all malnourished, and some had vision problems (one completely blind) due to the lack of nutrients available only in meat. Zerlina loves her kitty grass, but she's definitely a carnivore.

Hey, if you want your pet to be a vegetarian, get a rabbit or a guinea pig!
