Well, it wasn't easy with a 3 year old around. But free tires from garages more then willing to give them away. A few cans of spray paint from Walmart (paint after assembled to save on paint) and Cypress mulch (packs really nicely) from Home Depot. Adding in a Little Tikes sliding board that he is out growing and you have a home made fun, play area for a very active little boy!!
Put in a digging pit for rabbits. Nothing fancy. Just a tub filled with soil or sand so that they can dig to their heart's desires. This may curb their desire to dig their way out of the rabbit run. #rabbits
