Building a sandbox for my children

We went to the mulch yard and got 2 truck loads of sand. It is not totally clean, but it works. It had some small pea gravel and even some leaves and twigs. He also suggested we try the cement yard down the street. Their sand is supposed to be very clean.

ETA: We got a cheap kennel cover to keep cats and whatever out of the sand.

Don't. I did an they never played in it. Just attracts cats and holds water. If you do, buy the expensive sand for sand boxes. It is filtered. The construction grade sand could have glass, metal, etc depending on the source.

I built a small box for my son. Hes played in it a few times but doesnt really care for it.

Don't do it. It's a mess and they get over it quickly. Put up a tire swing instead.

Gonna be a giant cat liter box if you don't cover it.

I've thought about it before but we still had cats. Now that they're both gone I might build one. But my daughter wants a treehouse first. I was thinking of some combo treehouse/playset. Add a slide and a couple of swings. Maybe a zip line.
