Thanks everyone. I went to visit Alani and he's wearing an e-collar and resting comfortably on several towels and fleece fabric too. When I pet his head he started purring very loudly and it almost sounded like he was snoring. They are giving him sub-q fluids and he's on pain meds and antibiotics. To me his output didn't look very good. They hadn't even changed his urine bag yet and there was very little in it and it's blood tinged as well. For the tip of his penis to become so bad, he must've been licking himself without my knowledge for quite some time. Maybe even having the other 5 cats around was enough cause him more stress which contributed to his blockage. I received an estimate for PU surgery if my vet thinks he needs it. I know it's expensive but I think that it would actually save me money long term. If he blocked again then I'd basically be paying the same amount that his surgery would've cost once again just for him being in the ICU for a few days. I just want all of this to be over and Alani back home again and happy and healthy once again. I think that Blaze also misses him.
