I just came home from lunch and found my 9mo old kitty Henry laying on my bed, kinda looking half asleep, with her tongue sticking out of her mouth. Her eyes almost looked glazed over. Finally after petting her and talking to her she got up and started moving around...now things seem normal. I'm not sure if I should be worried or if she probably was just half asleep? It seemed odd the way her tongue was sticking out. Also this morning when I got up I could not find her and usually she is right there the whole time I"m getting ready...I was worried she might be sick or hurt. What should I be on the lookout for at this point?
