The weather here has actually been pretty rainy all month, so I don't think it's getting too hot in his room. Yesterday/today are actually the first nice days we've had in weeks. He's also in a room that gets morning sun and stays cooler than the rest of the house, so I'm thinking temperature is pretty constant.
He's eating like normal. He gets a piece of cooked chicken and a mealie every day, as well as his 2 kibbles. One he eats a lot of, the other only a few pieces each day. I'm still trying to find a second food he likes, this being the second new one I've tried. But it's been switched out slowly over time and I don't try new foods often. Poop and urine seem normal from what I can tell, and he's been running too
His bedding is fleece liners I made way back when I got him. Laundry detergent hasn't changed either. He's been on them since he came home almost 5 years ago. He only poops and pees either on his wheel (cake walk wheel) or in his little box.
I just wish I knew what to tell the vet so she could figure out whats up with him.
