Can I feed my cat multiple food brands? Will it upset their stomach?

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!

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!

As long as the diet he is eating us a balanced and complete diet appropriate for his age there is no reason to change it or offer variety unless he has a condition which may respond to specialist formulas such as kidney or skin disease. Variety tends to encourage picky eating so if he is doing well, continue with his preferred food

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.

You can switch their food but you want to slowly transition them to the new food. This means you want to start with mixing only a small amount of the new food in with the old food for a few days then over a 10 day period, increase the amount of new food while decreasing the amount of old food until you are just feeding the new food around day 10. By slowly transitioning them to a new food, it decreases the risk of causes an upset stomach. I hope this helps!

Yes, it is OK to give kittens treats, but make sure that they do not make up more than 10% of her diet. If you decide to change brands of food, make sure to transition slowly over a period of a few days to a week to make sure that she does not get any GI upset due to a diet change. I rotate my cats' food regularly and they do not have any GI problems, but until you know about Callie, I would take it slowly. I think rotating brands is a good idea as long as she tolerates it well. We normally recommend changing from kitten to adult food around 6 months of age. I hope that was helpful and answered your question. Thanks for using Petco Pet Education Center, formerly Petcoach.

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!
