I've read some questions here asking if cats can eat grass. Based on those, I gather that the purpose of eating grass is so kitty can get rid of hairballs or other indigestible "stuff" in their digestive tract. So now I am curious if cats should have grass available.
My situation: I have a 7-month-old shorthair kitten who is indoors-only, so she's never eaten grass. I also haven't found any hairballs so far, even though everyone says all cats do have them eventually. A few times, I've heard her as if she was about to cough something up, but it never happened.. although I catch her trying to eat dust bunnies every so often, so I'm sure she's managed to ingest some amount of bad stuff. The only time I saw her actually cough something up was a small piece of yarn she found. (Yes, I made sure to store all my yarn in closed containers after that!)
I'm concerned that in the future she might need to get rid of something, but won't be able to. Should I be providing some form of "cat grass" for her?
