Esp the dental part very well may be an age thing. We are actually thinking the thyroid has been going on much longer, but no one before our new vet knew to look for it because she has the opposite reaction to the majority of cats with it. The not being able to sleep with or cuddle her is going to be difficult esp since she likes to sleep above our heads at night.
I'm picking her up tomorrow afternoon. So I've actually waited to change out the litter and will be doing that tomorrow morning. Figured I was best to wait until the last possible moment to change the litter.
