Cat pee is like a lite skunk spray. It's also probably why our neighborly neighbors encourage their pets to use someone else's yard for a litter box. My dog almost killed a little kitten that found it's way into our yard. Fortunately, it made it to a thorny rose bush and I was able to get it and take it home...shaken up a bit. That cat never came back to our yard.

Now that our dogs are deceased, I have some neighborly neighbors cat pissing my children's sandbox. I guess we need a new dog!

And if a cat is using the sandbox for a toilet, then the kids don’t need to get anywhere near it. There is a variety of illnesses that can be lurking.

I have never known a cat to only urinate in a sandbox. They just bury the “other” business. Then children find these little hard nuggets while playing in the sand... ugh...
