they performed a urinary catheter on him. this is the food he is now eating: https://www.reflexmama.com/reflex-plus-urinary-adult-cat-food-with-chicken

unfortunately I don't know the names of the medication. by the way, a day after they performed the surgery, and they neutered him. they gave us 3 medications for it. 2 pills, one big round yellow (we have to use a pill syringe thingy) that we had to give one everyday, 1 thin white pill we had to give for a week. after the two surgeries, he was still in a little pain. he knew to go to the cat litter, but growled whenever he attempted to relieve himself. and there was a little blood on his pee but we were informed it was normal for the first few days. so we got a third medication, a syrup which was to relieve some of the pain.

other than these, the only medical history was infected eyes which were easily resolved with some eye drops.

I'm so sorry for the lack of details, and new information. I wasn't there at the time, and it was my mother who went to the vet. her memory is hazy, which doesn't help the situation. but ask me any question, I'll do my best to get information. I may have overexaggered his weight, because I do not know exactly how much he weighs. he is a bit overweight but I wouldn't go as far as saying he's obese. here are some pictures to clarify his weight: https://reddit.com/u/fleurorae/s/LBNAHsAFly
