Hi, just after other opinions. Our gorgeous boy is 19 years old and suddenly has lost so much weight. He is still asking for food, possibly drinking more than usual and has started peeing outside/next his litter tray. If I thought for a second he was in any pain I would take him to the vets draught away, however the journey stresses him out so much. I have spoken to the vets who have said they can do some bloods and investigations but I think he is just reaching the end of the road. How much would you have them poked and prodded at 19 or would you just keep them comfortable until the time came to make a decision. Any advice or thoughts would be appreciated.
