I'm getting a little worried about one of the cats. She woke up today with her inner eyelids appearing to be half open and they didn't go back down. Also she's been staying off by herself and when I petted her for a bit, she seemed to shiver.
I could be overreacting, but it seems like she's getting sick. Maybe a side effect of getting her shots? I had the vet give her the shots when I took them both in to get spayed.
