Miracle grow plant food???

I was just wondering if anyone knew if Miracle grow plant dirt with plant food would be a bad thing to plant some cat nip in?
I didn't know if the plant food would be bad for the cats or not.

If you're going to let them "harvest" it themselves, I wouldn't chance it. Otherwise it should be fine as they're eating the plants, not the dirt. Catnip can be such a weed I wouldn't think it would need very rich soil anyway.

If it says it's for use with vegetables grown for human consumption as well as flowering plants, then it's fine, imo.

i want to grow cat grass in a little pot, but i have discovered im no good at growng plants unless they are already out of their seeds

Catnip plants do not need that fancy of a potting soil (unless that is all you have!!)

We grew our caatnip in plain potting soil, with no additives. It eventually covered to top of the end table.

Thanks for the replies! I didn't realize that I had grabbed this bag until I got home, so I guess it's going to a friends house, and I'm off to get more!
I wanted Miracle grow potting soil because there it a kind that you don't have to water that much which is good for me because I tend to forget and then the plant dies. Yes the cats graze themselves, it's funny to watch. They sit in a line waiting their turn to get their highs. I had to buy another plant because they were destroying the original plant. I'm thinking of planting a row of plants for them but I'm worried that they will start to do their business in the planter and that would not be a good thing. So we will have to see I guess.
