He's 17 with thyroid problems. Been on medication for this for years and is now on just about the maximum dose.
Over the last 10 months or so he is gradually losing weight and now quite skinny. The vet wants him to have bloods done to see what the issue is. I have refused as at this stage of his life as it is traumatising for him and I wouldn't put him through anything else anyway.
This last 2 weeks his behaviour has changed. His appetite is ravenous. He literally scoffs 1 pouch then begs for another. (he has continuous dry food available but doesn't eat much) He yowls, runs into your legs, scratches the food cupboard.....anything to try and get you to feed him again. He is already on 4 pouches a day. This behaviour goes on and on. He still wanders around outside and has a catflap He goes in and out and in and out hoping each time his bowl will miraculously fill itself even though it is 10 minutes since his previous meal.
He does eventually give up and then sits/lies on the landing or the doorway. Not comfy on the beds like he used to most of the day. He does occasionally settle down and snuggle but I would say that 70% of time he is just miaowing for food. I hope he isn't suffering obviously and I don't know what to do for the best. When he is snuggled up to me purring and is settled on the bed it seems wrong to be thinking of putting him to sleep.
Any vet/vet nurses able to offer any advice?
