Just brought him back from the vet, he had to do a thorax drainage and spent two days taking IV diuretics, but he will complete the treatment at home, and on Monday we're gonna x-ray him to see what is wrong (we're guessing heart, but because of the liquids the previous x-ray couldn't see properly), but he is fine now.
He eats normal cat food, but I was going there twice a day just to give him Churu (motherfucker won't eat from the bowl, he needs to taste our servitude). I actually took a picture yesterday:

Hey, it's been a long while I've been thinking about making a website for my pets (I currently take care of 35 cats and 4 dogs), and I started working on it for real the other day. Gonna see if today I make a profile for him and his brother (https://lemmy.dbzer0.com/post/62154428). Let me know If you are interested, then I will link it when it’s ready.
