I recently adopted my cat from a shelter. when I met her there, she was a definite purrer, purring at me constantly. when I took her home, for the first few weeks she purred nonstop whenever I was in the room with her. however, she had a bad ear infection after that and was understandably in a grouchy mood, constantly scratching at her ears, swatting at people who approached her, and hiding under the bed. I took her to the vet and got medication. now (this is a month and a half later), her infection's cleared up but she doesn't purr much anymore: only late at night or early in the mornings. she seems more cheerful but is a little more easily startled/ anxious (maybe this has to do with the fact that I had to give her a topical ear medication once a day for a week, which she did NOT like). is it normal for her to still not be purring as much? what can I do to make her relax more?
