Need some sensible advice please.
My cat is 20 years and 3 months old. She is completely deaf, very thin, and smells. She drinks loads of water. She eats lots. She yowls in pain when I pick her up round her middle, so I pick her up under her front legs and she is fine with that.
I know that she is probably riddled with cancer. We got a dog three years ago and since then the cat has not come downstairs, she lives on the top two floors. She has a litter tray and feed in the toy room (yuck) which stinks. She is frequently sick. Her poohs are small and hard.
Having said she does not go down stairs, when the weather was hot during the summer, she started sneaking out past the dog into the garden and thoroughly enjoyed lying in the sun. She sometimes goes outside the door in the middle floor and wanders round the front garden for a few minutes.
Before we got the dog, the vet was very surprised that a deaf cat would ever consider going outside so I do not feel too guilty that her access to outside is severly restricted.
She lies on my keyboard the days that I am working. She lies on my DD when she is watching telly in the upstairs lounge. She comes on my bed for a cuddle and a dribble (yuck yuck) when I go up to bed. I overheard my DH referring to her as 'love' the other morning 
.
So - should I have her put to sleep? She is clearly 'sick', and a PITA, and probably very unhygienic to boot. We had a previous cat put to sleep when she was 20 (or rather, my mum made the decision) but she had virtually given up eating and drinking and was dying I believe. This one still wanders around wailing and moaning and dribbling. It is more the smell and the mess. But that is for me rather than her.
Your views please.
