Abstract
A pet pen for housing a pet is provided. The pet pen comprises a plurality of enclosing members with each enclosing member having a wall body and an opening end. The enclosing members form the pen by overlapping a portion of the wall body at two or more of the opening ends, and the pen width can be adjusted by adjusting the length of the overlapping portion. The pen width can be adjusted without removing an enclosing member.
