Here's some information for you from Google.com
Catnip is not fussy, if it was it won't survive long. Your standard sun to part sun and half decent soil will do just fine. If you are growing it for your cat, put a crown of chicken wire over the plant close to the ground. As the catnip grows through the wire and gets eaten the roots will remain intact growing new catnip. Make sure the edges of the wire are tucked in securely. It is very hardy, good to -40 so if the roots remain you will see it year after year.
Growing Catnip Indoors
Not recommended as it will get leggy.
Legginess is caused by poor lighting. If you have a south window and supplement that light with a gro-lamp you might be able to do it. I hope it works out for you and kitty.
P.S. Evidently cats don't get "high" from catnip. They feel, well, um, take a guess!
