Abstract:
A device for limiting access of an animal is disclosed. The device includes a housing having a sidewall defining an opening therein, and a housing interior in communication with the opening. The device also includes an opening-size selectable member engageable with at least a portion of the housing for restricting at least one dimension of the opening to form a modified opening. The modified opening allows passage of a first animal into the housing interior through the opening, and restrains a second animal from entering the housing interior. In one configuration, the second animal is larger than the first animal.
