I had Atticus out alone last night for lap time and he was on a practically white towel(actually off-white) . He peed as he usually does, but it had like an orangish tint to it. What could this mean? I am going to have him out in a clear box later to see what is going on with him, it could have been just the towel but I'm not sure, I hope he's ok because going to the vet may be a stretch. I hope he's ok,also, because I love him.
