Hello all,
Unfortunately, here in Brazil we have no Akadama or Kanuma.
But...
We DO have something that the seller calls "Brazilian Akadama":

AND...
Following this link (that uses cat litter as bonsai soil,)
bonsai4me.com/Basics/Basicscatlitter.htm
I also have found an Argentinian lava soil from Patagonia that is sold in Brazil as cat litter. People say wonders about it... Testing it on some cuttings:

This link above is in Spanish, and the first one in Portuguese.
So, how many people here use cat litter as bonsai soil? I am curious!

Here in America, its tough to find cat litter without perfumes and chemicals. However, turface, which is a hard fired clay that doesn't break down, is easy to get and similar to cat litter.

I like using Pumice. It is cheap and works quite well.

I have it in my mix.

Where in Brazil are you?I am in Brazil a few times per year, moostly Soa Paulo & Parana state.

Leatherback, I live in São Paulo, and I own a fineart printing atelier here.

Ah cool. Will do.
