I didn't notice much yesterday for the fluid bubble, I thought it was gone quite quickly. Today I noticed a small bubble form, so I'll check to see if it's all gone already. He still seems very weak, when you pick him up there just isn't much fight in him, but he's always seemed very mellow and laid back as well since I've seen him so I'm not sure how much of that now was "old age" or something more, like being dehydrated.
He was more active at my mothers though so he's certainly weaker than he was. He is mainly just sleeping in his carrier, but around 2am last night I began being able to get some foods into him. Little bits, a few licks of water or yogurt, a small piece of avocado. This morning, he ate more than the other feedings... a small piece of banana, some avocado, a spoonful of yogurt, watered down yogurt off my finger and watered down blocks off my finger - about 4 finger tips of watered down lab blocks. While he was grooming himself more and could walk a bit better over the fleece when left alone, there wasn't much fight when I pulled him out or when I sub-q'd him, even though he squeaked with pain and should have fought. So, I'm not sure really where he stands, I just know he's eating some which he would not do last night.
I'll work on getting a video if I can.
