Jen, all things considered, I would let him go to the Bridge. You, of course, know what is best in the long run. I think we have the ability to NOT let a pet suffer. If you do decide to let him go, HE will be at peace - no more pain and discomfort. Cats can be quite stoic, so you never really know the degree of pain. I wish they could talk.

Good luck with your final decision. I know you will do what is best.
