If you are reading this article, then you probably have a stinky cat. Cats eat food high in protein and that makes their flatulence especially foul. Gases build up in their systems if their digestive tracts are taking a long time to digest the food they eat. You can't stop your cat from passing gas, but you can take some preventive measures to cut down on her unwanted habit.
Change your cat's food slowly over the course of a week by mixing in a high-quality food with the food you usually feed her. If she's eating better, then there is a less likely chance that gases will build up in her system. Call your vet to find out a good food for her. It's worth the money.
Do not feed your cat milk, or at least cut back on how much you give her if you do provide her with milk. Lactose causes gases to build up and is difficult to digest for cats.
Keep your cat from eating things outdoors. This may require turning an indoor/outdoor cat into a strictly indoor cat. You can also put a bell on her neck so that she has more difficulty catching wild critters. She may still eat insects, but this will help cut back on her eating foreign foods that cause gas.
