Help! Bladder infection??

Hello, I have a 2 year old male neutered black cat and he was fine before today. Today though, he has been going in his litter box and trying to pee unsuccessfully. He just sits in there and cries then comes out and licks himself while growling. He seems like he's bloated after he tries but then after he calms down a bit his belly softens up. I tried to feel his lower abdomen when his belly was softer and I didn't feel any type of hard distended bulge or anything. He didn't even try to get away or cry out. He was just like "hmm? Whatever." and the walked away. He doesn't like it very much when he is bloated but he just meows. He doesn't growl or anything. I took away his litter box because he keeps trying every 5 minutes and then comes out hurting. He still walks around normally and seems fine otherwise.

I believe he has a bladder infection, but I can't get him to the vet until tomorrow morning. Is there any way I can make him more comfortable or feel better until then??

EDIT: p.s. he now seems to be continuously bloated, please help! I'm so worried!

I just have no way to get there :( The vet I take him to is miles away and I have no transport :( I was going to make an appointment for as soon as they opened but they are closed and I am unable to make one. I am waking up (If I even get to sleep tonight) super early and waiting impatiently for the minute they open to take him in as early as possible. Is there anything I can do until then? My grandmother had a cat with that problem that passed away recently and she gave me a can of UTI special wet food and I gave him some of that. He ate it normally. I think he's been drinking water. I saw for sure that he was drinking it a couple days ago. I WANT to take him to the vet, I want to tonight, but I have absolutely no way to get there :(

Thank you for the vibes.  I just hope he can hold out until tomorrow 

PS. Should I give him back his litter box? He's looking for it but he seems to just be hurting himself when he goes in there...

Thank you for the information. He just went in his litter box and tried again to unsuccessfully urinate but at least this time he wasn't crying out in pain :( He keeps trying every couple of minutes. He's getting into his "pee stance" Head sticking out of the covered litter box. He just tried to pee on a blanket as well. Poor baby It does sound like what he has. I'll stay with him and hope I can at least comfort him until tomorrow. I hope he can hold on :(

Thanks guys. I'll do whatever I can. I appreciate the advice and will try to get him there asap. I'm getting offline now so I can spend time with him and try to get to the vet. Thanks again guys.

UPDATE: Alright guys! I got him to the vet in time and he is being treated! Got a call from the vet saying that he just had a 'snotty' build up at the end of his little...you know. No stones or anything, thank goodness! :) I pick him up tomorrow night. Thanks everyone for your support! He's going to be OK! :D

Thank you everyone so much! He seems to be much better today and I've been keeping a close eye on him. I'm using the clumping litter right not so I can see exactly how much he is urinating. He seems to be at normal levels :) I'm only giving him wet food from now on and I've even been mixing in a little bit of warm water with it (since it's cold) and he's been eating it all up, so there's no way he's dehydrated now! :) Thank you all so much for your concern, I really appreciate it!

I've read every single one of the articles you guys posted for me on here and I'm now definitely ready to take better care of my baby. I'm vowing now to tell anyone who feeds dry cat food to their cat what I've learned on here. If I can prevent even one more cat from suffering this, I'll be happy!

I'm so mad that I didn't know about this beforehand, it might have saved a lot of trouble, pain, and worry. Again, thank you all for being such a great help, and all your information will not go to waste! :D

Thanks again everyone, now I need a little advice again -.-"

Since my cat's been home for about a week I've been feeding him nothing but wet food with just a few little crunchy treats a day. He was eating the food eagerly when i was feeding it to him earlier in the week but now he's slowing down. I believe it's because before, he got dry food at least once a day. He goes after the little crunchy treats like crazy, so I think he misses his dry food. He still eats it, but it takes him all day to do it (I feed him twice a day, once when I get up, about 7 - 9 am  {depending on weekday or weekend} and then again at around 5:30 pm. He gets a can all together a day) I was just wondering if that's normal.

Ok, now here the thing that's really worrying me. He's still got a little blood in his urine, and I can tell because he keeps peeing in the tub for some reason. The vet said that would be normal for a while, but is a week a little too long for it to be happening? His litterbox is in the bathroom at night though because I have birds and if I leave him in the living room he tries to attack them at night.So he pees right outside the litterbox when that happens. But no worries about him being in there at night, because he's seen the bathroom as 'his room' ever since he was a kitten! He goes in there to go to sleep all by himself. I just close the door at around 11 pm and open it around 6-7, when I always get up to...go pee.

Anyways, he also seems to be taking a lot more trips and peeing a little each time, instead of when we first brought him home and he was just plain peeing a LOT. He seems fine in every other aspect. He runs, plays, sleeps in his normal spots and in the same amounts. The only other thing is I picked him up yesterday and he meowed at me. Which is normal for him. He usually meows like once and then starts to purr when he gets comfortable. (He is QUITE the vocal kitty) But this time he meowed a few more times and then peed on me. I'm not mad at all, I'm just glad he's still peeing! I clean his litterbox like 3-4 times a day, because I'm trying to track his litter usage, but it doesn't seem like he's using it a lot. And when he does, it's all against the wall where he just jumps in, like he's barely holding it and he's jumping in, peeing in like 2 seconds and then jumping out.

The thing is, yesterday I took him outside on his little harness. He's a primarily indoor cat and he gets scared of the outdoors, but I just take him outside and let him wander around. He's been getting braver every time. Plus I don't let him go outdoors on his own because there are a huge amount of stray and outdoor cats especially around my house, and I don't want him getting into a fight and hurt.

The point is, when I took him out, he squatted and peed a decent amount. Is he just having a hard time controlling his bladder because of the catheter? Because like I said, he didn't really have that problem when I first brought him home.  Now because of the numerous small amounts of urine he keeps producing, I'm worried. Is it just an aversion to his litterbox? Because like I said, he didn't have that when he first came home either.

Also, I keep feeling his belly periodically throughout the day, and he's never bloated except after he just eats. Also, it seems like he producing less feces, but I have changed his diet to only wet food, is this normal as well?

Sorry about the long message, i just like to get all the info I can out at first so you guys know what going on and don't have to ask too many questions so I can get an answer faster :)

Any info would be appreciated!

The vet gave me some meds. 1/4 of a pill called Acepromazine 10mg and a liquid called Buprenorphine. They told me to give both to him twice a day for 5 days, which I did. He actually is peeing more I think now. Yea I would say the clumps are about ping pong ball sized. He seems like he's peeing less frequently and more, if not in his litterbox. When he pees in the tub, it's a good amount. The only thing I'm really worried about now is the fact that there's still a little blood in his urine. He actually does pee in his litterbox more than he did at first I think. I think I'm mistaking it for not a lot because I'm cleaning it out so much. I will call the vet tomorrow and ask them about it, as they are not open today.

Thanks for the advice :)
