About 5 years ago we took on a cat that had been abandoned by a neighbour.l - a long haired ginger Tom
He was in a sorry state; wouldn't go near anyone and had to be neutered and shaved.
We were originally told he was probably about 3 but when we moved vets they thought he was much closer to 10-12.
We also suspect he has been hit by a car at some point as he walks very stiffly and has never groomed himself resulting in annual shaving under sedation as he won't let anyone do it for him.
He probably sounds like a nightmare from this description but we love him!
However over the last year or so he has been increasingly searching for food and although eating tons is getting skinnier and skinnier. What is probably the clincher for me is that he's soiling round the house now and not bothering to use his litter tray.
He had tests about a year ago for the weight loss and was put in thyroid meds but it just seems to be getting worse.
I've probably answered my own question from the above but time to let go?
