In November 2012 my lovely aunt passed away leaving her elderly cat. My mum took the cat to live with her. Sadly, my mum passed away in April last year so we brought the cat to live with us. She wasn't in the best of health so DH and I took her to the vets to rule out any major problems. She was found to have a b12 deficiency (which we have under control with steroids) but other than that all was fine. In the summer of last year we noticed she was passing blood in her urine so rushed her back to the vets. Since then she has had one urine infection after another, she has no control over her bladder and wee's wherever she sits/sleeps. We have had to ban her from most of the rooms in the house and as a result she now sleeps on the stairs. The hallway smells of urine. Me and DS gave her a shower yesterday as the vet warned of urine burn. This morning she smells so bad it's hard to be near her, her lovely white fur is tinged with brown stains. DH thinks the best thing to do is have her PTS, I'm crying just thinking about it but am I being selfish keeping her going because of who's cat she was/is? She is 18/19 and has arthritis but is still eating, washing and grumping her way along. It's just the bladder issues that are a problem.
