With regards to lizard litter I have used that for a number of years with my bearded dragons and have been pretty happy with it. However beware of the following:
"NOTE: Lizard Litter has changed! The Original formula is "Derived from the famous Kenaf plant of the beautiful Mississippi Delta" The NEW formula is white fir and eucalyptus chips. Same size and texture, but it IS a wood-based product now."
I am now stopping using it due to the fact that I don't know about the properties of the two woods they are starting to make it from. Bearing in mind how certain woods can cause problems for snake (cedar being the prime, but not the only example), I would suggest further research before making the change.
The above statement is about the original lizard litter. It should be noted that there is also a Desert Blend Lizard Litter made from ground English walnut shells.
And also a Jungle Mix which is organic, natural, nontoxic, pest-free. It purports to contain a unique blend of:
sterilized virgin organic soil, fine grain sand, vermiculite, peat moss, orchid bark, and green tree moss.
Lizard litter can be purchased locally at pet stores such as Petsmart, and online at
