This is basically everything you’d need but the critters. There are 3 tiers with “ladders'' for exercise and animals' natural climbing instincts. We attached hardware cloth around the bottom because our rats kept trying to chew the plastic base, which we replaced and is new. It is still perfectly intact.
Included is a glass rodent water bottle with a little float so you can see when it’s getting empty, a cotton hammock, a corner litter box, some bedding, rat food, and some wooden toys.
