This is our miniature version of El Capitan. It combines tough bamboo slats as its base, leather, rubber, paper, plastic, cotton and sisal rope, metal, both hardwood and softwood. The white plastic tube is filled with treats that your bird can see through the ends and small peephole. The slats can be refilled eventually but this wall should last a small bird (e.g. small conure, cockatiel, parrotlet, etc.) several months—MUCH longer than others on the market. Measures approximately 10” long by 6” wide and weighs 0.8 lbs.
