Horatio, saya guna yang rounded crystal, white color and a bit of blue color. Tak pasti jenama apa. Semalam ptg pi beli kat pet wonderland great estern mall, the price around rm18.00. CAri FP atau PP but bila tanya the PW staffs, diorang tak tahu pun bendalah tu.

I put all inside the open litter box, not sure about the amount/height that i need to put inside. Tengah malam tadi I peeping diorang. One of the kitten (tomok) dah start guna untuk poo2, but the rest came around the litter box, because of the sound of the crystals. And they start pulling out the crystal. Bet me, they can "menyeluk pekasam sampai kepangkal ketiak". Dari segi nak membersihkannya senang sebab crystal akan melekat, dan u hanya buang poo2 yang melekat tuh saja. Maybe I will mix with some sand to make the crystal heavy.
