Mojo had been neutered and was woozy and grumbling (very vocally). Made me wonder if I'd done the right thing. As I write this it is the following morning and while he seems to have lost his balls, he has certainly found his voice and is doing lots of vocalising. He's full of beans this morning and probably needs a good run for an hour or two, but for the next week we're on orders for only three or four ten minute walks so his stitches have a chance to heal.
