My cat has gas after eating. Is his multi-flavor food the problem?

Poor Rodney! You may want to try a probiotic mixed into his food once a day, such as Forti-Flora - this often helps with excessive gas. Another option would be to try a different food, as there may be an ingredient in his current diet that doesn't agree with him - there are companies like Natural Balance and Wellness that make limited ingredient diets that may be a better fit for him. If these things don't help, then it would be a good idea to have him checked by a vet to make sure that nothing else is wrong. Your vet may also recommend a prescription GI diet, or a hypoallergenic diet to see if this is more effective.

It is very possible the food is causing Mac some GI distress. Other possible causes could include illnesses, infections, parasites etc. A good first step is to bring in a sample of Mac's stool to your vet for an exam and to check for parasites/common GI issues. If he checks out OK, looking to switch him to a different diet or trying out a feeding trial with your vet may help if there is an ingredient he is allergic to. It is best to transition to new food over a period of 7-9 days, gradually adding in more of the new and less of the old, to avoid further GI irritation.

Extra gas can be caused by a sensitivity or allergy to the diet (most commonly to the protein source), not necessarily to the wet or dry formulation. Consider trying to feed Callie strictly one diet for the next month or two to see if it changes her flatulence. If that does not help, try a different diet for another month or two. It can take at least 6-8 weeks to determine if a diet change has made any impact on Callie. Any time you make a change in diet, be sure to do so gradually by mixing the old and new foods together over 5-7 days.

It's possible there could be something underlying such as a food allergy (protein sources can cause allergies in some pets!), or even something such as parasites or an infection causing excess gas. It would be a good idea to bring in a fecal sample to your vet to check for the most common causes of GI upset, and if nothing is found consider a food trial with your vet to rule out any possible food allergies that could be contributing.

The most common cause of flatulence in a pet is dietary intolerance. It looks like the food you chose just doesn't fit well with her intestinal flora! If flatulence is the only change, and it is something you can tolerate, you do not necessarily need to change her food. But most people would decide to try out another food instead of having a stinky cat!

Thanks for using Petco Pet Education Center, formerly Petcoach! Diarrhea can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications for diarrhea depending on the results. Good luck! Hoping for a speedy recovery!

Congrats on your new cat! A bland diet of chicken will typically help diarrhea if it's caused by an upset stomach or GI illness, but because it didn't, it is more likely due to something else. Zues may actually be suffering from intestinal worms, which is a common cause of diarrhea in cats. I would take him into the vet today for an exam along with a sample of his feces. The vet can examine his feces for signs of worms, and can prescribe a deworming treatment for him.
