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

A friend of mine suggested rice. Another friend tried it, with good results, so I did the same. Plain ol' white rice, though I don't think it much matters. Very inexpensive, as well. If humidity is an issue with this choice, or cat litter, it'll be one only in a more humid climate. 

If going with cat litter, make sure it's unscented. If it is scented, your cat/s might take an interest in sniffing around it, and, well, you get the picture. 

If not fill your stands with mercury. If you have any mercury left over mix it with equal parts vodka and lime juice and drink it while listening to the results of your labors.

Wouldn't be the best choice. There's a very good reason they stopped using those mercury filled glass thermometers decades ago...(mercury toxicity). Unless  of course there's some other kind of mercury you're talking about.

Put dried fish in your stands,are fish dampening ?

Gold dust can be used if you have some extra gold lying around. Make sure it's well sealed so it doesn't attract gold bugs.
