Sounds good. The closest vet I know to you would be Toronto (The Links Road Animal Hospital- really good with small animals.) But I don't know anything in the Kitchener area, unfortunately.I'm from Kitchener.
The owner has his hands full and I'm really skeptical he would take them back, though I did ask about my concerns and he said it was fine in his hands.
I'm going to wait a week and see where things go.
