The shelves that the plant trays are on are metal rack type shelves and difficult for the cats to climb. Hoping they leave my stuff alone.I'll try to get a pic once it's done. Nothing tremendous, mind you - just a table with grow mats & trays, and a wooden structure holding grow lights. Unfortunately, there's not a lot of extra room in there. Then we'll have to figure out how to keep the cats out of it. What did you do about that, Cap?
