"My growing spot is in the old garage that's attached to the house."
Hmmmmm, I have a refrigerator in the garage for summer use to hold veggies. I put a cardboard box on top of the fridg with some padding in it for the cats. There is a chest freezer next to the fridg, the cats can jump onto the freezer then up onto the fridg and sleep in the box. Cats do seem to like high places.
