I put a little toy seal in his bed and he tried to lick it, thinking it may be Max, but he then realised that it isn't. (his mum burst into tears when he did that, the feeble old sheep that I am). I've left it in there though for some extra company. I'm trying to decide if I leave him lying on the new bed, which is quite thick and fleecy, or if I put that underneath and the heatpad on top of it (it won't stay flat, but don't imagine that's too serious), then Swampy's grot old vetbed which smells even more of Max on top of that, so it would still be soft (the new bed only had him on it for 1 night). The only thing is the new bed is puffy so he sinks into it in his own space. The old bedding arrangement was quite flat with the heatpad and maybe he may notice he's alone more (??).
He woke up and wandered around, tried to poo and didn't (he went last night but his tum's hard; I emailed the vet about that too) and had a good purr when I cuddled him. He did seem a bit disoriented and actually walked all the way into the kitchen and wee'd in Max's tray.
Don't know about Laura but if I have to go out for a few hours, I may call her and see if she is available as right now don't want Swampy to be alone much. Already this morning he's slept less and walked around far more than he usually does.
