Hi everyone, do any of you have a building or construction background, or are you more inventive/creative than me??? Here's the challenge. I know there's an answer out there somewhere
I REALLY need to construct an outdoor doggy litter box. I found a couple of portable ones available online but I don't want something that involves using and having to change out kitty litter. Therein lies the dilemma...
We have two dogs (15 lbs and 55 lbs), who are together destroying the small (but slowly enlarging) corner of the yard where they have been trained to relieve themselves. Fortunately, we have a large enough side yard to place what I envision as a large doggy litter box, maybe 10 or 15 feet long by 5 feet wide. What I cannot find anywhere online are suggestions for how to build this masterpiece.
Here are my requirements...
It needs to be approximately 10 or 15 feet long x 5 feet wide. It will be on a patio with no protection from the elements. We live in Southern California so the weather is never extreme other than hard rain at times. It needs to be able to drain the urine w/out it building up, down in the box, in a way that makes it a smelly nuisance. I want to be able to rinse the box out thoroughly with the hose, without filling up the box.
What I need your help figuring out is what should be inside the box and how to allow for drainage, and what wood to use (or how to treat it) to withstand the elements.
A treated plywood bottom with railroad tie sides (or similar) would be fine, or I could use pine or similar for the sidewalls. Inside I would put pea gravel as the top layer for anti-splashing (while urinating) and easier #2 pickup. If I have to replace or add gravel once a year, so be it.
So far, my plan does not allow for drainage. Do I need to raise the box off the cement ground a couple inches, drill holes in the plywood bottom, and let it drain onto the cement, where I can rinse it weekly into the nearby patio drain? I'd want most of the urine to be absorbed and not freely flow out the bottom, at least until I need to rinse the pebbles. Do I need to do something more extravagant than that? How thick (deep) would the contents of the box be, and should there be a layer beneath the pea gravel and what should it consist of?
Any suggestions very much appreciated.
When this project is finished, we can re-carpet the downstairs. Holding off for now only because with our current system the dogs sometimes track in dirt and bud by stepping in the mud where their urine has killed the grass.
