My Hyper Cat

My smallest cat, Nola, who's also usually the calmer one, has been on edge this week. She's obsessed with a corner in the living room and has been spending several hours (that's right, hours!) a day staring at it. I even caught her standing on her back legs in order to look into the light socket! She regularly runs away from the corner and over to me, and then back again, like she's trying to tell me something. Hmmm...I hope there isn't something living in the wall! She's also a cat who growls a lot in her sleep. Overactive imagination? If only I spoke Cat.
