Trying to Identify Cat Food

My partner and I are fostering a cat for a local rescue. When we first started fostering our cat, Lulu, she had extreme tummy upset with extremely loosing bowel movements. Our vet wanted to focus on figuring out her feline hyperthyroid (which we have figured out with meds yay) before working on her food.

Our rescue recently gave us a donated bag of food that has really worked for Lulu. Her bowel movements are solid. No more carpet cleaning every other day lol.

The problem is nobody knows what brand of food they gave us. It was donated so in a container already. And the rescue doesnt have record of who donated it (so we can’t ask them).

We’re hoping maybe someone here can direct us to the brand. We originally thought it could be Hill Science Diet Digestive I/D but (from what we can see on the internet) the kibble doesn’t match.

Here is a link with the picture of her kibble. It’s all this shape.
