The past two nights he's been back in bed with us and climbing up to our faces along with his brother, Richie.
And he's been spotted eating kibble. Yes, dry kibble. He's spending more time walking through the house, he's much more obvious than he was pre-surgery. I would guess that his pain level has greatly subsided from the past months/years.
There's no more drooling and he's once again grooming himself.
It's all good.
