We did this when we kept our rabbits in a shed. Just used a piece of linoleum a little larger than the dimensions of the floor. We didnt' secure it, just laid it so it would curl up on the sides and at the side opposite the one door. Our rabbit cages were suspended, so we scattered a bale of straw on the floor. Cleaned it out about every 3-6 months (not as frequently during the winter). It worked great! When we were finished, we just rolled up the linoleum and threw it away. You can get remanents fairly cheap and although I do dislike waste, this linoleum was ...... too.... pungent to be used ever again in any way!
