I've taken Mr C off this once and for all. He was so ill and weak ast week, limp, like a little fun fur nightdress case emptied out, vomiting spit and barely able to walk, that I couldn't stand it any more & binned it. Also he itched horribly.
What else is there to ease the pain of his leg arthritis? He is much more perky since he's been off it, giving it the giddy goat all over the furniture.
