Reptile basics make hides big enough for adult female boas, and and dog bowl works just as well for reptiles. As DrDooLittle said, you can always make stuff yourself. Bus tubs and cat litter bans can make great hides or water bowls. Creativity and resourcefulness are a reptile owners best friends haha. A few of my friends even use 10 and 5 gallon tanks as water bowls in their big cages.
