I have 3 cats, all indoor. they have never been outside since I got them except in the cage for vet visits. I have no intention of EVER letting them be even semi-outdiir cats.

so my question is this - you see all kinds of adds for Special Diet cat food and such because they arent getting certain nutrients from eating grass like they would do normally as an outside cat. is this true, and if so can cat grass grown in the home work?

I know every time I come in the house with fresh cut grass clippings on my feet, they dive bomb me and I cant even move to get the stuff off of me lol

so is it a good idea for indoor cats to have something like the cat grass, or does it not even matter?

thanks
