Hi, all. It seems I'm at a crossroads with my 18-year old kitty. She has stage 1 kidney failure and an awful cavity that makes it hard to eat and causes her a lot of pain. I've read that extreme dental disease can cause onset of kidney failure. I've also been told by my vet that putting her under to take care of her teeth is risky to her already compromised kidneys. So... Which road would you all take in this situation?
