I've dosed him twice via the Logic gel - half a tablet makes only a tiny bit of powder, and I've mixed in a bit of the gel and smeared it on his paw, and he licks it off - it can work if absorbed through the tongue
funnily enough, Gill, this is a drug given to humans, and in the US is not licensed for veterinary purposes, as it is an opiate, and liable to misuse
I'm not sure anyway if he is in any pain when not moving, though the swollen leg is bothersome - he is spending most of his time dozing on a folded Goose down duvet on the floor in the sitting room, and getting off only to eat, drink or use the tray - I don't know if that is because moving is painful or difficult or because he's drugged up, but either way he seems comfortable enough for now
