Urinary cat food making cat puke

[Vinorosso74]

Our male cat was diagnosed with bladder stones a couple of weeks ago so we were told to switch to a prescription diet to dissolve them. Purchased a huge bag of Hills c/d and some wet pouches of c/d and Royal Canin s/o. He was fine for the first week but since then was vomiting and wouldn't eat the food (understandable if it's making him puke). We've switched back to his normal food to get him to eat and have his meds and he's not vomiting and is so much better! I'm going to see if I can do a gradual switch to the dry food (wet is completely different so will need a different approach!). He likes food and isn't generally a fussy eater.
I have been in touch with vets, waiting for them to get back to me. I know he needs urinary food to resolve the issue.
Has anyone has had a similar issue as reading reviews puking appears a common issue! Any brands which don't cause vomiting?

I think you should go back to the vet. Does the cat have to have S/O - our cat preferred the C/D urinary range as gentler on the stomach

Is your cat an only cat? We had a cat on a urinary diet - but as one of 5 cats it made things very tricky.

We found by trial and error

• the dry food was eventually accepted - I think it was Royal Canin c/d urinary care
• the wet food was very hit and miss
• The Salmon pouches were reluctantly accepted
• the chicken pouches were sometimes accepted
• chicken in a tin was disliked
• the beef was loathed
• the one called "loaf" was hated and made him throw up

We could only ever get ours to accept the dry food. Twelve years later and he’s just fine on a normal wet diet and not the specialist one. I think it’s just trial and error.

He's the only one. I've been in touch with vets but no response yet.
He's on the c/d dry (well supposed to be). I got the wet s/o and c/d to see what he'd eat.
Found a brand called Concept for Life on Zooplus which claims it's easily digested (then again they won't say causes puking) and they do a small bag. I don't particularly want him eating this food long term as it's full of crap!

Unfortunately if your cat has a tendency to urinary crystals the chances are that they will need to to be on the food for life. This was our experience as every time we tried to phase it out he ended up with the crystals again and on several occasions he got a blockage and had to have emergency surgery.

Eventually, once the crystals were dissolved, we found a happy balance whereby all of our cats ate the prescription dried food and then he could eat non-prescription wet food.

I think I read somewhere that you shouldn't mix c/d and s/o food because they work in different ways. I cannot remember which way around it is but one of them dilutes the urine to prevent crystals forming whereas the other changes the mineral composition to prevent crystals forming. However if the cat eats both they counteract each other - ie if the urine is diluted the mineral food won't be strong enough.

Mine couldn't tolerate RC or hills either but was ok with Virbac U2

Mine has Purina urinary food and is doing really well on it - no issues whatsoever in to years now.

I've had far too many cats with urinary problems.

First 2 I switched to dry urinary cat food and they were happy although we did get occasional flares.

Latest I just thought, when the advice is to increase her fluid intake, why am I giving her dry food not wet? So I've fed normal wet food, cat milk for extra fluid and it's been OK.

If you think trying to get them to eat urinary food is bad, you should try renal. The cat made it clear she preferred death to surviving on any brand or flavour of renal food. So I gave up and fed her whatever she wanted.

Thanks all. Still not heard back from vet. They used to be great until they were bought out !
Anyway, I'm going with a gradual switch on the dry food and will try introducing the wet slowly. He's already booked in for a follow-up ultrasound in February.
I hate prescription food. Our last cat had to start on hypoallergenic food. She then became diabetic as her pancreas was damaged. Of course she had to eat before we gave her insulin. That wasn't fun. She was a lovely cat though.
