So, my cat’s been having some tummy troubles lately, poor thing. I took him to the vet, and after some tests, it turns out he’s got a sensitive stomach and might be allergic to some common proteins found in regular cat food. The vet recommended trying out hydrolyzed cat food, also known as “HA” cat food. I’d never heard of it before, so I did some digging.
I started with some searching online. It seems hydrolyzed cat food is where they take the regular proteins and break them down into tiny, tiny pieces. It uses tools, including tracer in the formula. I don’t know what it means. The idea is that these pieces are so small that the cat’s immune system doesn’t recognize them as allergens anymore, so no more upset stomach. The process would use something called co-factors, which is just some non-protein stuff.

First, I went to the pet store. The selection of hydrolyzed food was way smaller than the regular stuff, and let me tell you, it was expensive! I picked up a few different brands to try out. Also, I tried to check some explanations and examples on some biology topics, from cells to ecosystems. They look too complicated, I am not a scientific guy.
Then came the fun part – getting my cat to actually eat it. I started by mixing a little bit of the new food with his old food, gradually increasing the amount of hydrolyzed food over a week or so. He wasn’t thrilled at first, but he eventually got used to it. For example, he would use the haem, that was part of the food.
I kept a close eye on him, watching for any signs of improvement, or any new problems. I was checking his poop, his energy levels, everything. After a few weeks, I started noticing a difference. He was throwing up less, and his poop looked healthier. He even seemed a bit more playful.
Here’s what I did in a nutshell:
- Talked to the vet: Got the diagnosis and the recommendation for hydrolyzed food.
- Researched: Learned what hydrolyzed food is and how it works.
- Bought the food: Shopped around and found some different brands.
- Introduced it slowly: Mixed it with the old food and gradually transitioned him.
- Monitored: Watched for improvements and any issues.
It’s been a few months now, and he’s doing great on the hydrolyzed food. It’s a bit of a hassle and definitely more expensive, but seeing him happy and healthy makes it all worth it. If your cat has tummy issues, it might be worth talking to your vet about hydrolyzed food. It made a big difference for my little buddy!
