Switched cat to wet food due to FLUTD, no poops!

On Sunday I took my cat stinker to the Emergency vet,
He said he had a blocked bladder, catheterized him and said he may need a diet change (which he never got back to me with) he also had bunched up intestines in the x-rays.
They gave him barium meal, it went all the way through his body and he was able to poop it out.
Then on Wednesday he wasn't peeing again, so I took him to his vet, he stayed there for 3 days with a catheter and they started feeding him new prescription wet food (he always use to just eat dry food).
Since he has been home (fri afternoon-mon afternoon) he has been doing well with his FLUTD and peeing a lot. However, I haven't noticed him pooping! There have been a few little droplets but I'm not even sure they came from him (we have 3 cats, the other 2 are my moms).
I am starting to get worried, I called my vet but she was off today.
Is it because of the diet change? He always took big poops sometimes twice a day because he ate a lot but now is limited to 1 can of wet a day.
I need some advice!
Should I try a laxative? Like a hairball one?
I have already spent $2,100 in vet bills and can't do any more. He is only a year old I can't bare the thought of having to let him go.

Wet food has a lot less fiber and is more digestible, so you'll see less poop. Cats don't have a natural need for fiber, so this is usually fine. But some cats whose bodies have gotten used to the fiber in dry food may become constipated. I think I would put him in a separate room for a day or 2 so you can determine how his poop is going through. If you think he's constipated, add some canned pumpkin (not pie filling mix, just pure pumpkin) or baby food squash (might be easier to find and is in a smaller container), about a tablespoon a day divided into his meals, to provide fiber.

If he'll eat it, add extra water to his canned food. For FLUTD cats, the more water the better! And more water can also help ease constipation.

Thank you for your help! I always put a glob of food in the middle then surround it with water and he eats and drinks it all
I just noticed that he had some crusties on his butt (gross I know lol) but I'm thinking maybe he has really bad diarrhea and I am mistaking it for pee as I scoop?

If he seems to be acting OK, you can try what Willowy said and isolate him with a litter box to make sure he is pooping. I can tell you from experience that switching to a low or no-grain wet food will make their poop tiny. I have been giving my old (14+) cats mostly wet food as of a few months ago. I leave a quality hard food down for grazing but only have to add to it every few days. They love their wet food and the litter box action has been mostly pee. The poop is very sparse and tiny balls - less than 1/2 inch round. 

You Vet may not charge for a follow-up visit. They can usually tell if the cat is constipated by feeling the belly with their hands - nothing invasive. Perhaps your Vet or someone here can tell you how to try this for yourself. 

Once this episode is over, I'd ask myself what led to this with such a young cat. It could very well be diet. What were you feeding him? What are you feeding him now?

Good luck

He acts fine. I'm just worrying so much because he is my baby.
Trust me I have constantly been asking myself how he could have FLUTD so young.
The vet found a lot of bacteria in his urine so that may have caused it.
I use to have my own house and moved back in with my mom about 6 months ago, so I know it is probably stressful for him. My mom has a Siamese who can't accept him and he is quite scared of her. He may have gotten the bladder infection through holding in his urine due to being afraid to walk around the house with her when we aren't home. I am now keeping them separate, locking her in my moms room while we aren't around.
Also I insisted we get her cat on a prozak-like medicine which she has to take the last time we got a cat.

Oh, and he was eating a new food my mom got its called basics, it's high in protein .. She just switched them to that a few weeks ago so it may have been that too

He pooped!!! Yay thank goodness haha his body just isn't use to wet food

...Cats don't have a natural need for fiber...

Oh, yes, they DO1

Ah, well, perhaps I should say very little? A wild cat's natural diet is only about 2%-3% fiber but I suppose that's not the same as 0%.

No, if they're healthy, they really don't require much. But it's the "if they're healthy" part that is the modifier there.

And that 2-3% is a combination of fiber AND carbs (from stomach contents of prey).

The fact is that in the wild, the amount of non-protein, non-fat, non-mineral content of a feral cat's diet (based on analysis of 27 studies from around the globe, using studies that covered at least a year and where cats had no access (5% or less of the total diet) to human provided food or garbage) was just 2.8% on a dry matter basis.

So while our indoor cats that have suffered a lifetime of damage from eating a species-inappropriate diet may require fiber to help their proper motility, cats naturally do not require much in the way of fiber in their diet.

The felineconstipation.org article on diet/fiber/prebiotics/probiotics is interesting, but IMO misses one very important point. Cats in the wild are eating a daily probiotic, they're not feeding the healthy gut bacteria with prebiotics. They're not eating psylium husk, guar gum, beet pulp, slippery elm bark, etc. They're eating mouse guts and fur. They're eating live (healthy gut) bacteria with every meal.

Similar results for my near 17 year old Meesha (Siberian). She had been almost exclusively on Hills y/d dry food for her thyroid. Starting Feb 13 she was hiding, not eating/drinking, laying in the litter box, not being social with us, not asking for little bites of our human foods (she loves chicken, meat and pork we eat). Took her to the vet numerous times for intravenous fluids, kidney numbers climbing, potassium down, phosphorous up, white blood count up (indicating inflammation), feeble, dehydrated. By Feb 15th my vet was discussing end of life options. I was down, thinking my little friend was dying. But I got her to eat Albacore tuna, Wild Pink salmon, both in water and both contain potassium. She did not like Renacare potassium gel. She got better, slowly. Then a sudden turn, hiding, squatting everywhere, laying in the litter box (by now I am fanatic about keeping it clean, and checking her fuzzy back end). Then I noticed a small, gel like mini-jelly bean discharge near her urethra, slight ting of what looked like blood on it. I collected it, freaked out, got her to the vet immediately. At the vet she peed again and passed a similar discharge.

My vet said she had never seen anything like that, and felt Meesha was sloughing off/out part of her bladder. Kidney numbers higher, white blood count increasing. Again, talked about end of life options, even that I could have it done right then. I just couldn't decide that for her right then, or the next day. By that Saturday Meesha was acting normal again, and eating better, asking for treats, acting more like herself, though a bit feeble. She was eating regularly, but is not interested in any "cat" food, nothing but the Albacore tuna or Wild Pink salmon. I decided to try lean ground beef, browned in a pan only with a bit of water, because she shouldn't only be eating tuna or salmon. She took right to it. Eating multiple servings a day, now a mix of ground beef (with some Hills y/d kibble mixed in), tuna or salmon. Two weeks AFTER the vet suggested euthanasia options I had her back for follow up, kidney numbers still elevated but stabilized, white blood count normal, potassium getting better, gained a 1/4 pound of weight (she is only a six pound kitty), hydration better. Vet was VERY pleased, surprised even, and I'll have Meesha back in four weeks for another followup.

And, after ALL this I notice she poops a lot less frequently, though daily still, pees a lot more (taking in more water), and the poop has MUCH less stink to it, if any at all. She is active, engaging, eating, asking for treats, meets me at the door again, much happier. So, hopefully it was just a serious bladder blockage that she managed to pass, and at the same time I got her on a much better diet, and I get to enjoy her sweet demeanor for months, maybe years to come. All that after spending near $3000 at the vet. And my near 19 year old tabby mackeral, Maynard, is also responding better to whole/wet foods versus the dry typical cat food.
