I'm looking for this kind of litter box too. Price range mcm Kak June ckp and most pet stores carry this. But I'm not so sure nak beli ke tak because tgk yg diy punye kalau buat sendiri frm kotak plastic tu is cheaper but masalahnye fikir nak tebuk lubang tu mcm payah.
Let us know when you get one k, nak tau jugak if you dpt yg murah
Petsmore dkat shahalam tak tau ada ke tak but i know there's one in cheras (i think).
