I bought this with my initial purchase of the 6x2 cage & cover. I love having a space for all of the food & hay, and by doing so, most of the mess in contained in the kitchen but, I wish I had purchased one of the larger sizes. I have 2 boys, 2 1/2 years old, so they’re full grown. I keep a fresh salad and veggie bowl, dry food dish, dried salad dish, & hay holder inside so it really doesn’t leave much room for my boys. It does make it much easier & quicker to clean the cage so if your thinking of adding this item, I’d suggest you consider one of the larger ones if you have the space. All in all I do love it.
