So, my kitty, charlie, has been chewing on my houseplant. When I looked in the pet store, I noticed their "anti plant-eating spray" listed the active ingredient as rosemary. So my question is, do you think it would be safe if I just boiled some rosemary in water and sprayed that on the plant?? It says the deterent is that it tastes bitter, so I'm thinking it would be ok to make it myself....
What do you think?

I don't see why not! Then you know that it doesn't have any chemicals or poisons in it.
