Abstract: An enclosed litter container for animals, the container having upper and lower enclosure portions which are joined together to form an enclosed space. The upper enclosure portion includes an opening to provide access for an animal to the enclosed space. The upper portion also includes a depending flange which fits within a widened rim of the lower portion of the litter container to restrainingly couple the two portions together and to seal the joint between the portions to prevent escape of urine therefrom. The upper enclosure portion includes an outwardly bowed compressible resilient section which, when compressed, causes the depending flange to move out of restraining engagement with the widened rim of the lower portion to facilitate separation of the enclosure portions. The depending flange and the widened rim portion are configured so as to direct urine away from the region of the joint between the two enclosure portions and toward the bottom of the lower enclosure portion which contains the litter.
