Here is the link to the product that I found. Let me know if it is safe, if it's not, I'll throw it out.
"Pine wood shaving, cassava starch, alfalfam straw liqui mix (water, sodium alginate, potassium sorbate, propionic acid, honey, glycerin, propylene glycol)."
How that qualifies as food is beyond me.
Eventually they went inside of it, and they were squeaking a little, then A LOT. Then a minute later Taffy comes charging out of the igloo and he was POed!!! He was clacking his teeth SO loudly, i have never heard him do it that loud before, so the snak shaks gone.
I have since sent my sister to GL so she can make more educated purchases for her "nephews."
