Ugh! Now Oscar has urinary issues going on!

Well I posted about 3 weeks ago that my cat Katie had a uti. She is doing great now and goes in on Friday for her recheck UA. Well now tonight I got home after going out to dinner and while I was preparing the puppy and cats dinner I noticed Oscar going in the litter box a little too frequently. Sure enough I checked and there were several good clumps but then 5 small dime sized clumps. I checked his rear and no blood, but I took him to the e vet anyways. He's acting completely normal otherwise, in fact he wanted to eat dinner before we left.
Well the vet checked him and he looks great. His bladder was too tiny to get a sample from though. She used the ultra sound and noticed the bladder wall is slightly thickened and possibly inflamed. There was some debris noticed but it didn't look like stones but possibly WBCs due to inflammation or sludge. He was caught very early she said. We decided to treat proactively as my other kitty did have a bacterial infection. He is on clavamox and a urethral antispasmodic. They also gave me buprenex if needed. Oh and they gave some sq fluids to try and flush the bladder out.
So far he seems fine. He wanted to play with his feather toy when he got home and he finished dinner and drank some water. He went to the litter box and left a normal clump as well.
I am so frustrated and worried. I know the cats are slightly stressed because of the new puppy. Well we got the puppy a month and a half ago. We are teaching the puppy to leave the cats alone, which he does. He never bothers Katie but Oscar instigates play but batting at the puppy and running away. This is how he used to play with our old dog and they got aling great. I think we aren't going to allow any play at least till this is all resolved.
I'm trying everything to keep the cats stress free. They have plenty of high perches. Several water dishes and litterbox locations as well. I had feliway before getting the puppy but never noticed a difference but I ordered some refills on amazon tonight. I also ordered some bachs rescue remedy, and uti support supplements the vet recommended. The cats are on a 75 percent canned diet with water added to the canned food. They also get a small amount of dry because they were kibble junkies and I am currently trying to break their habit. They are already stressed right now so I don't want to add more stress by going kibble free yet. I don't know what else I can do. I am so worried Oscar will block, but the vet said we caught it early. Doesn't mean it can't still happen though. I thought we were in the clear and now this:-(

Sorry to hear about Oscar, but it seems you caught this in time. Good for you for being such an observant mommy!
Ritz is prone to stress induced UTIs, so like you, I'm very observant of what is in the litter box.
It seems you're doing everything right, from trying to reduce stress to transitioning to 100% wet. What brand of wet food are you feeding? I would suggest grain free food, something low in carbs (carbohydrates include, obviously, grains but also cranberries, peas, potatoes, etc.). No fish at all. If the food contains turkey, all the better: it contains a relatively high amount of l-methionine, which is naturally occurring in meat and is a natural acidifier. (I fed prey model raw.)
For stress, I'd suggest adding l-theanine. It is a mood relaxer. Honestly, I'm not sure it's helping Ritz with her stress, though she hasn't had a UTI for about a year.

Thanks! I just feel so bad like I caused this by bringing in the puppy. Oscar is normally very laid back and always enjoyed playing with dogs but maybe the puppy is a little too much for him. The pup is getting better though so hopefully things will turn around. This morning Oscar was his normal self begging for breakfast and rubbing up against me. He did have two normal sized clumps in his box, and a few small ones. He has been going in the box frequently and producing only a small amount. I'm thinking he has that urge to go but nothing is there. He isn't distressed though and not acting in pain, just maybe irritated. I gave him his antibiotic, antispasmodic, and buprenex this morning and he ate and drank. He is enjoying watching the birds outside right now.
I am so scared he is going to block though. The vet said she didn't see any obvious stones but his bladder was so small that there was no urine to highlight a stone. I'm hoping the meds will kick in soon. It took a few days with Katie but we had to switch antibiotics a few times before finding one she could tolerate.
As to food, Oscar is on natural balance fat cat for dry. I don't really care for natural balance, but it is actually working and he went from 18 pounds in February and is 17.2 pounds yesterday. So slowly he is losing. I've tried everything! Raw was a no go as both cats refused various brands. I tried grain free dry and canned, but Oscar gained weight. So now he's on fat cat dry which is a small amount of his diet, and various canned. I try to stick to grain free, but he is picky so sometimes fancy feast or friskies will be fed. I also add 2-3 tablespoons of water to the canned food for more moisture. I try to not feed too much fish but feed it occasionally because I never had issues with these cats until now. I looked at the ingredients on fat cat and unfortunately one of the ingredients is salmon meal:-(. The vet was talking about royal canin SO for the cats. I am not a fan of the Rx diets as their ingredients are poor, but it am desperate to make my kitties feel better and avoid costly issues.

Well we are about the same. Oscar is still going to the litter box frequently, but he is producing urine each time. Sometimes it is a clump about half the size of his normal clump, but then I will also see quarter sized clumps. He still has a fairly good attitude and he doesn't vocalize when going. He comes up to purr at me and head butt me. He is eating though there is a slight loss of appetite I think due to the clavamox. He had some diarrhea last night which he never has. I am still feeding a combo of dry and canned as I don't want to stress him out more by stopping the dry. We are going to work on that when he is better. I am adding water to the canned food as well as bonito flakes. He eats some and then lifts his nose at it. I've gone through at least 10 cans this weekend to try and encourage him to eat more canned. He hasn't been at the water bowls much which there are several in puppy free locations. I am worried that this is going to exasperate the issue. They puppy is at doggy daycare today so hopefully the cats can chill and relax. I also have a call in to my regular vet. I want to pick up a new bag of LRS and a line so I can do some sq fluids at home to help flush him out. Plus I mightvwantbto switch to zeniquin like we did with Katie because of his tummy upset and the fact that zeniquin is once aday. I did have a bag of LRS in my first aid kit along with a line so I hooked it up and gave a little bit. I need more needles though so going to stop by my vet. Plus the bag is close to expiring next month and I'd feel better just having all fresh stuff. Anyways I got about 75 Mls in him before he was too much to hold by myself. I will give more when my husband can hold him. They gave 200 Mls at the e vet so that is my goal. I am so terrified that he might block, so far I think we are ok but blockages happen so fast:-( Here's to hoping we can get this fixed. Oh and I also got him started on d mannose and glucosamine chews for UT support and a calming supplement with L-thianine and colostrum calming complex. He does seem more relaxed and so does Katie after giving those. Now I just have to wait for the feliway and bachs rescue remedy to come in the mail. Wish me luck that he doesn't block. I am so stressed over this and trying to not show it is hard:-(

Yes, it is hard to not show your feelings. Bonito is of course a fish--does he like any other kinds of treats?
Continued vibes.

Thanks! And yup I know bonito flakes are fish. Not ideal but I have to keep him eating first and foremost as he is a slightly overweight cat and I worry about fatty liver disease complicating issues.i mix the bonito flakes in canned food and he will lap it up and get moisture which is needed. We are going to work on diet after we are in the clear though. Honestly I don't think it even was the fish in the food as he had a full wellness work up in February and his bloods and urine were perfect.
He is still slightly subdued but seemed normal after we went to bed playing with his toys and jumping in the window. I switched to the zeniquin because of his upset tummy on clavamox. I also picked up a bag of fluids and have been giving him some sq fluids twice a day to help flush him out. He is also still getting the prazosin and buprenex too. I am tryi to keep the stress level down but he really hates being medicated :-(
This morning he had an almost normal pee clump then about 2 hours later a smaller clump maybe the size of a quarter. I felt his abdomen and he doesn't mind that and his bladder is small and pliable at this point. I think he is still having irritation and having the urge to go but nothing's there. I started him on the UT support from vetriscience and composure which has the l thianine in it. My vet said to keep a close eye on him and if he isn't starting to improve by Thursday, she wants to see him ASAP. I just want my happy mischievous kitty back:-(

Well, I took Oscar into my normal vet yesterday because Oscar continued to make frequent trips to the litter box with small clumps and a few that were a bit larger but still half normal size. Anyways, they kept him for a bit. My vet did a thorough exam and they also snapped a quick X-ray. His bladder continues to be small, but there was no evidence of stones and the urethra was clear of any blockages. Unfortunately the bladder was too small to get a sample and of course he didn't want to leave one while there. My vet said he is in no immediate danger as of now, but we need to continue to monitor him. His appetite is probably down because of the clavamox that we have since stopped. He was having loose stools and probably an upset tummy. I took him home and he actually ate a bit better for dinner. He ate a whole can of chicken fancy feast(I know crappy food but it works for tempting kitties) I also added a couple tablespoons of water too it for added moisture. He continues to get the zeniquin, prazosin, and buprenex. I also gave him 100 Mls of sq fluids last night.
This morning I found a few larger pee clumps and two smaller ones. He ate a good amount and got all his treatments. I am hoping this will clear up soon. I have the feliway coming in today so hopefully that will help to cut the stress. Hoping things will turn around soon and not get worse over the holiday weekend.

My philosophy is when in doubt, go to the vets. But I tend to catastrophize things. And, I have pet insurance.
Continued vibes.
PS: Fancy Feast Classic is a decent grocery store brand. Low carbs, relatively high protein.

Thanks! I also tend to take the pets in whenever I am not sure. My husband gets annoyed but blockages aren't something to mess around with and he said to go ahead and take him in. Anyways, Oscar seems brighter today. He had two larger normal sized pee clumps and is not going to the litterbox frequently anymore. He's chilling out by the slider to the backyard watching the birds. The puppy is at daycare today so the house is stress free right now. I do think the feliway might be helping a bit, plus I've been giving rescue remedy as well. He ate a good amount of canned food, but still ate his dry. He isn't ready to go dry free yet but I think we will work on that after I know we are in the clear for the uti issues.
