Tarnicus: His typing skills have also been limited due to injury. "When it rains, it pours" seems to be the appropriate analogy for the health condition of our household. We just got back from taking him to the vet and he is on anti-biotics due to an infection from fighting. Maybe there is a lesson in here for me also, but I doubt I'll take heed of it until it smacks me in the face :D
He isn't very happy about being sentenced to indoor healing time but he'll just have to get used to it. The vet was surprised by his size and commented on his weight, which was 8.5kg, just shy of 19lbs!! Given that he has lost fat and put on muscle, I'm quite impressed. He was most likely sired by a feral cat and it shows in more ways than one.
How many days will he have to remain indoors? My previous cat started going crazy if he wasn't allowed to go outside for a few hours. Come to think of it, I haven't encountered a single domesticated cat that didn't go crazy at being prevented from going outside.
