Mine are both shorthair indoor cats. I recently had to groom my girl cat mainly because she had a streak of poop on her back and my male I bathed only once but he stunk so bad that the owner put him in a stinky cat carrier. I got him off craigslist and the owner was nice. I just didn't like the smell that was coming from him lol....I just wasn't sure how often....He was in perfect shape he gets his teeth brushed and also just got his rabie shot when we got him. So he is good for the rest of this year.
