Am I missing something here? I'm new to cats and recently took one into my home. Am I supposed to be providing plants for him? What exactly, am I supposed to be doing for him? He eats Avoderm, Solid Gold, Aristocats and Fussie cats. He has his litter, his toys, his "landing pad", scratching post. He goes to the vet once a year - what else should I be doing, and am not? He gets lots of playtime of course.
