Glad he's eating something Billie, even if it's just a little ham. If he has his cone on he'll be fine - he'll probably sleep his way through you being gone, with the after effects of the anaesthetic, his body recuperating and the stress he's been through. It'll probably be worse for you than for him
The groomer I first used for Sorrel was at the vets too, and she was great. Since I've moved to a different part of the country I haven't really managed to find one I trust totally. It's so tough as every time you try a new one you're worried it's going to be yet another bad experience. It would be easier if vets would recommend one but over here they're not really allowed to As Sorrel has a real fear of boarding kennels the larger ones aren't an option either.
