Is it safe to mix two different wet cat food brands for my cats?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 4 years and 3 months old | 11 lbs

Is it ok to feed my 3 female cats 2 different brands of wet food? They like purina pro plan but i worry since it contains wheat gluten. They also like Natures Instinct but its out of my budget now to buy this for a whole weeks worth. Thank you.

Yes, it is absolutely fine to feed your cats a mix of two foods! Purina ProPlan is a high quality diet and wheat gluten is not a cause for concern. If you decide to mix the two foods together, try to be consistent by always mixing them rather than switching back and forth. Sudden diet changes back and forth can cause vomiting and diarrhea in some cats.

    Your cats are lovely! Both of those foods are fine as they are complete diets. The only problem I could see would be that switching between 2 foods could upset their tummies. But I think they should be fine, just keep an eye for runny faeces.
