I hate to be a downer in this thread, but I need some solid cat advice and I know y'all will be honest and fair. My 20 year old kitty boy has gone blind and is missing the litter box. He eats well and doesn't hide. I struggle with whether to take him to the vet to have him put down or wait. He doesn't groom and has had CRF for over 5 years. I know the end is near, but should I have him euthanized or let him live out his days with palliative care?
