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

Thanks for using Petco Pet Education Center, formerly Petcoach! That would be fine as long as that does not upset her stomach. If she develops any vomiting or diarrhea then stop at that point as that could be the reason. Otherwise it should be fine. Good luck and have a good night!

Purina Proplan is one of the three highest quality foods I recommend to clients. The other two are Royal Canin and Hills. They follow veterinary nutritionist guidelines and current evidence based research. Gluten intolerance is extremely rare in pets and gluten content has no bearing on a food's quality. It is also important to not overfeed protein as it can harm the kidneys, so foods with higher meat content may not be better. I hope this helps.

Yes it is okay to switch back and forth between those two different pouches as long as she tolerates it. If she starts having loose stool then I would just pick one and stick with it. Most cats can tolerate a small variety but some cannot. I hope this helps!

Abrupt diet change can cause vomiting and diarrhea in some animals. If your kittens don't seem to have a problem with multiple food brands then it would be OK to feed different brands but if it causes any gastrointestinal problems then you should stick to one brand of high quality food.

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.

Great question! No, it is not recommended to mix up a cat's food. This mixing of food causes GI upset in the form of vomiting and diarrhea, and this is the reason why it should not be done. I would stick with one brand of food for Newbie. Good luck, I hope this helps!

The brand doesn't matter but is always a good practice to change food gradually. Abrupt changes to Leo's diet could result in gastrointestinal disturbances that lead to vomiting and/or diarrhea.
