FELINE PINE!!! No silica dust. Made from recycled pine cones. Lasts longer than scoopable. Use only 1" in the box. Remove solid waste daily. Urine and odors are absorbed by the pelletts. Once pelletts turn to sawdust, dump the whole box and start over.

I had to use it because of my 16 year old cat Mollie Rose (RB, 2009) had kitty allergies. Once she died, I kept using it and can't imagine using anything else.
