We don't have lots of storage inside our house, because we've been doing so much remodeling, especially in the basement. I'd love to have a storage room, but for now . . .
So we've got the brooder cage for new chicks, and the lid, hanging on the left, then a really ancient sled, in case we get enough snow some year, then under the a/c unit is the larger dog crate, and then the medium-sized one. We used the crates for a long time, but the dog now has his spot under the stairs and doesn't need another enclosed area to call his own. Heck, he won't even use the dog house we bought for him to use outside!
