Is it a good idea to mix specialized dry cat foods for my cats?

Updated On September 23rd, 2025

Pet's info: Cat | Maine Coon | Male | neutered | 11 years and 8 months old

I have two cats, a 7 year old and an 11 year old. I've been giving them a mix of three types of dry food (Science Diet urinary health, Blue Buffalo healthy aging, and Blue Buffalo Indoor hairball control mature). Is this a good idea to mix these three together in their bowls? I just want them to get the benefits from these products as well and not get tired/develop an allergy from just one type of food constantly. Thank you!

So it’s ok to mix your food but it’s not likely that the cats are getting any real benefits from any of the diets. The diets are formulated to be fed as the whole meal every time. The diets also contain only a certain amount of the active ingredients that are unique to the formula of the diet and if the pet does not eat the full amount, the total level ends up being below threshold and the pet receives no benefit from the active ingredients. A better option would be to pick one diet and stick with it. That way the pets will receive the full benefit from the diet depending on what is your greatest concern. Supplements can be added if you’re worried about hairballs or joint health. The urinary components are unique and you are not likely find any supplements for urinary health. I hope this helps and please feel free to post any additional questions.
