My cat who passed away used to fart all the time. She was such a delicate looking lady, but her farts were foul. My boy farts sometimes, but they don't make me run for the hills. My dog on the other hand has awful sulfuric farts that follow you. I blame it on the fact that my mom likes to give her eggs.

Your cats farting might be a dietary thing, or it might just be a farter. But if it worries you, take your kitty to the vet and they'll be able to help you.
