When Oscar had his UTI last year, there were just a few crystals, which cleared up in a hurry - but there was blood in his urine even when the infection was gone.

No, and I can't see a way to make poor Bobo bleed...I don't think for a moment the vet would have done that. I think Bobo already had some blood in his urine, since he had been having such trouble.

The Clavamox will start working soon, and Bobo will feel better - and your dad will sleep better!

Give Bobo a hug for me!
