Im glad he's ok too. for future reference. chinchillas with UTIs stretch and strain to pee. it looks like the are trying to push it out.
He could have a stone, and that's where the blood is coming from. If he does have a stone, I'm sure he's very uncomfortable and in pain. If it's a UTI, I doubt it's so much painful as a nagging ache, which sometimes feels worse.
I don't know if UTIs are the same as in chins and in humans...but UTIs can be EXTREMELY painful.
