I've been noticing that my cat has been getting progressively weirder the last month or so. Really talkative...hiding in strange places around the house. Sleeping ALL over the house (usually she always had one or two favorite spots), jumping on tables and sitting in strange locations she's not allowed. She's also been really loud, meowing and asking to get into rooms of the house that she never goes in. She's being really active, but sometimes I swear she's out of it: . Her companion kitty died earlier this year, so she's been alone now for many months (she's always been around other cats, she she's used to them). Do you think that she's getting depressed, ansy from being alone? She's 12 years old...only a little geriatric (doesn't seem senile though). Sometimes I just wonder if she's getting lonely. She's in good health and everything else is going fine (litter box behavior is perfect). She just seems really fidgity and ansy. Just wondering if any of you have gone through this?
