Finally a food for my kitty with a very sensitive

My adopted feral kitty had horrible stomach issues and her stomach bloated/swelled and the litter box stunk like you can't even imagine, or she was allergic to everything - and where her ears would itch and she would scratch constantly. After trying six different prescription foods this is the first one that worked!!

What happened?

I've been buying this product since my cat was diagnosed with having a thyroid disorder. I haven't been concerned with the price even though I have notice an increase with both this product and the hydrolyzed protein. However, this is the only food that my cat will eat without it making him severely sick. Lately, this product has not been sold in stores, not even on chewy. What exactly is the issue, is the ingredients? I do not understand how this product just stops being stocked in stores, when it does become available it's gone before anyone gets a chance to purchase.

Price Increase

Last month, and all of the previous months we paid $20 a bag less than this month. Have you increased your prices?

primary ingredient is corn starch

First ingredient is corn starch, 2nd ingredient is hydrolyzed poultry by-products aggregate. No other "meat" is listed. It has an unattractive odor and hasn't helped with my cat's constant vomiting for which it was prescribed. He eats it reluctantly. I think it is overpriced for the lack of results and lack of protein. Protein content is listed as a minimal 24.5%.

What changed?

I've been feeding my cats a combo of Ultamino and Hydrolized Protein for four years (except for several times when it was out of stock). This was prescribed by vet soon after cat adoption from shelter to cope with sensitive tummies. But for the last month, they both vomit several times a week -- undigested food soon after morning feeding. They don't seem to be sick or uncomfortable. And they enjoy and tolerate their evening feeding of canned food. Did something change in the formula?

Works I guess??

My cat gets urinary crystals, so I had to switch her to a prescription diet for that almost a year ago. She immediately threw up the royal canin SO food, so I switched to purina for a little while, until she developed skin allergies to that and refused to eat. After trying some others (science diet, rc urinary+hydrolyzied) she was still having allergic reactions and throwing up. I’ve had this for a few weeks and she still refuses to eat it on her own. I have to give her individual pieces like I’m giving her a treat, and even then she’ll only eat maybe a tablespoon at a time. She hasn’t been throwing up or having worsening skin allergies, but whether it’s the smell or the HUGE pieces, she will not eat this like food. I wish there was a wet food version that I could try because she might actually eat that, but hopefully my vet and I will be able to find a food she’ll eat and not be allergic to soon.

Inconsistent quality

This food has been a life saver for my cat with food sensitivities/protein allergies. However I find that the quality of food varies from batch to batch. Some bags I purchase are great, and sometimes I buy a new bag of food, and my cat reacts to it right away (gets itchy, moody, stool changes, she is obviously in pain). It's like there is no quality control at RC whatsoever. Getting seriously tired of this....

Only food she can eat. She likes it. Wet version??

My kitty has IBD and eventually kept developing allergies to everything I tried to give her over time. Novel proteins, raw diet, you name it. I was using the Hills Z/D before because I REALLY didn't want to give her a kibble diet (especially bc she is prone to urinary issues), but she eventually started reacting to even that over time. She improved noticeably when I switched her to Ultamino. Unfortunately it's still not enough - she started having problems again after a year on this and is now on steroids and chemo (chlorambucil) for early stage small cell lymphoma and IBD. But the vets say this is the most hypoallergenic option, so I am glad it exists at least. However, I REALLY wish they would make a hypoallergenic pill pocket! SO many of us who need to use this RX food end up needing to medicate our purrbabies, and it would make life so much easier for them and us if there was a way to pill them with a pill pocket or even wet food. Please PLEASE work on developing a hypoallergenic wet food or pill pocket, or both! One last note - I really appreciate that I can just call and speak with a nutritionist at RC when I have questions. It was them more than my own vet that impressed upon me the importance of eliminating all other potential sources of allergens in her diet. I assumed it was OK to occasionally give other treats that as far as I knew didn't bother her system, but I didn't fully understand how allergies develop and wasn't warned enough by the vets that she could develop allergies to even the most hypoallergenic food if given a non-hypoallergenic treat occasionally that would make her body associate them. I wish I'd known sooner, but I'm glad I at least found out, thanks to a RC nutritionist.

Did the formula change?

My cat has allergies and stomach ulcers. She's been on Ultamino for about four years now but with the latest bag with the new packaging, she's been throwing it up. Has the ingredients/formula changed? Not sure if I should just give her more time to acclimate or change brands.

Keeps my cat's tummy issues at bay

My cat has tummy issues, we think it's a parasite, but just in case we give her this food plus probiotics. Just wish there was a treat or wet food option so she doesn't get bored so easily! Also this food has the distinct smell of tomato soup, but I wouldn't call it a bad smell especially because cat food normally smells much worse! Also it's super expensive, but what can ya do about that?
