My beautiful moggy boy, Disco, is 11 years old and I've noticed in the last couple of weeks that he is walking rather stiffly after getting up, and he's started using one of the garden chairs to get on and off the table, almost as though he knows his old legs can't leap like they used to. He's a happy and healthy cat otherwise, still spending lots of time outdoors and hasn't gone off his food or displaying any out of character behaviour. I wondered if there's any over the counter treatment I can buy for his joints or if it'll be a trip to the vets? Including a pic so you can all see how gorgeous he is!
