Well, three ingredients, if you count patience, because each one is felted by hand, and that takes loads of time and care. - The natural odor of the wool will attract cats to the Cat Cave. - Healthy, breathable and odor-resistant natural fabric. - Reacts to changes in body temperature - your cat will be delightfully snug but never overheat. - Handmade in Nepal from 100% natural, organic materials. Materials: 100% Merino Wool from New Zealand Cat Size: Up to 25 pounds Dimensions Height: 15" | Length: 20" | Opening: 9"
