Sissy and Hootie are sisters but lately Sissy has been acting a bit like she's a momma cat and Hootie is her kitten. If Sissy is laying on my lap and see's Hootie lay down somewhere she will jump down, run to Hootie, lay down and start grooming her. If they are laying together in the computer chair and I go over to pet them Sissy will start meowing at me. I've seen momma cats do this when they have a litter of kittens. This isn't the first time Sissy has acted this way either. It's strange.
