One of the first things you should do if you think your cat has too much gas is to make an appointment with your veterinarian. Bring a fecal sample in with you to be checked for parasites.﻿﻿ The fecal exam will look for parasites such as coccidia, roundworms, and hookworms that could be causing excessive gas. This is a simple and routine test that can also be done on a yearly basis, especially if your cat goes outdoors.
If your cat has a clean bill of health, then you should look at its diet.﻿﻿ Ask yourself: Has there been a recent dietary change or indiscretion? Did you change your cat's food or treats? Did your cat get into something it shouldn't have eaten? Any of these things may be causing excessive gas. If your cat gets different types of foods on a regular basis, consider keeping a food journal to track the relationship between diet and your cat's gas.
The best way to keep your cat's farts to a minimum is to feed a quality cat food that agrees with your cat and to minimize dietary changes. Regular administration of probiotics may also help.﻿﻿ Avoid feeding items containing lactose, such as milk, and take your cat in for regular check-ups with your veterinarian to catch any intestinal problems early. Regular administration of intestinal parasite preventatives is also recommended in many cases.
