Kritterz Large Hollow Hideaway Discontinued :( Product Description: Critters of all kinds appreciate a little privacy. Our Hollow Hideaways are the perfect retreat for small animals, reptiles, amphibians, and fish. Made of pet safe, easy to clean resin with realistic, hand painted details. RattyRat's Review: This item is a very beautiful little hidey hole that works great for young rats and is easy to clean. Unfortunately it is too small for adult rats, although some smaller females can use it.
