thinking of creating a small "yard" out of a plastic kiddie pool, lined with sod for the piggies to roam and snack in. However, my concerns are will the sod survive? Will mold grow because of the plastic bottom? Should I create small holes in the bottom of the pool to allow for ventilation? Can I cover it in some way to keep out the roaming cats from using it as a toilet? I have considered the option of creating one indoors as I have the space. They have a 3 level cage with another level at the bottom for storage that would make an excellent little playground for them. But again, not really sure if that is possible without creating a moldy mess. Any tips would be appreciated. Especially because I have a "black" thumb...lol

is under the trees and gets lots of leaves in it. The fountain leaks in back and the water keeps getting lower and lower, probably a hole in the liner somewhere.

So we are thinking of filling in the pond w/small red lava landscaping rock on bottom (lots of this in a garden we are redoing and I dislike it), then river rocks on top w/the fountain still bubbling up in the middle. Any suggestions on how to do this properly so that the water will not leak out, and we don't have to continue to refill the water level? Thanks for any ideas, I live in Wyoming so there is LOTS of snow in the winter and it is only used in the summer months.

Now we are also going to redo the front of the house w/a full length deck (eventually a roof over it). Have some cinder blocks, and thought about using wood decking over them w/the blocks as support. Do we need to place the blocks in sand to level? Or how should we proceed?
