Thats an old cat right there. Its almost as old as i amhave. I think this is oldest i have heard of.
The story of this cat is so painful but cheer up man.
Talk to the vet and hear what they have to say.
Although i don't like cats but this story is a touching one. Accept my condolences.
It is likely Merlin will be put down; There is no cure for old age. I think we are leaning towards euthanasia as it is probably the best decision for Merlin. Thanks for letting me know you don't like cats, possibly not so relevant at this moment, but you're entitled to voice your opinion.
Be strong!!
