 Well, the cats go out there and use the lawn, so I have these little piles of thatch everywhere. Okay. Because a lot of the times I tell people to use sand, okay? Oh, okay. Yeah, put about two inches of sand on your lawn, and you can do that with either Bermuda or Zoysia. And I know you have Zoysia. And it'll just work its way down into the soil, and that's the way to aerate it.
