Oscar is one of my ex-fosters, who went a bit off colour the back end of last week, but the vets thought it was just a bug, gave him ab's and Vitbee, but he didn't perk up. Bloods were done on Mon that showed his kidney levels aren't good and there are some other bits that aren't right (low white cell, so definitely some kind of infection), but the vet feels it is ARF, so he is spending 24 hours at the vets on a drip, and they are then going to see what his levels are like. He isn't that old, my vet estimated him at 8-12 when he was picked up 16 months ago, but he has had lots of problems, bless him.
