Wanted: Cat Teeth Cleaning Info

On her Facebook wall, Cindy posts: “Okay cat owners/lovers I need some feedback. Both Milo and Thor have gingivitis and need teeth cleaning. Cat teeth cleaning costs roughly three times what it does for humans. My husband says no cat owners he knows have their kitty’s teeth cleaned and says it cheaper to just get two new cats. I really hope he’s kidding about that part. My question is: Have you had your cat’s teeth cleaned?”

Question: Can anyone help Cindy?
