I was told to put Kitty Litter in my new speaker stands. Was he joking?

I guess i realize he was NOT joking, but it seems strange. I've always heard sand was best. He told me to get unscented kitty litter and fill em all the way up. The stands are 29 inches with 4 columns (2x2). Monitors are 23 pounds each.

Anyone done this with a positive result?
Renowned speaker designer Andrew Jones uses kitty litter in his stands at the audio shows. If it's good enough for him, it's good enough for me. I put lead shot in the bottom of mine, then filled them with kitty litter. Works great!
You can go to your hardware store to purchase a bag of sandblasting sand. You can get it in different sizes and it's nice and dry. 
I have melted lead and poured it my legs of my stands worked great didn’t even burn off powder coat !
Depends. Where did he tell you to put the kitty?

Kidding aside, kitty litter has been used since the beginnings of this hobby for those who couldn't afford lead shot or something better. Some even preferred it to sand.

All the best,
