My two garter snakes (117cm and 85cm) love this cave. They are often the whole day together in their new favorite hiding place and sometimes protrude only the two heads of the hole ^^. the design is different from the picture, the cover consists of the entire upper part so well out of the walls. The base has a knew prevents slipping of the lid. This design enables easy cleaning of the cave or the replacement of moss. If the snakes have to be brought out by this type of construction is also much better than a cap as shown in the product image where you would have to rely purely from above. the optics, the materials and processing are great. There is also plenty of moss for this large cave there. Very strong buy recommendation.
