Reusable quick sifter |
摘要 |
A flexible, reusable quick sifter for use with a litter box which employs litter of the clumping type. The sifter has an expandable or stretchable netting secured to a hydrophobic surface across an opening such as a slit in a central area of the box. On lifting, clumping litter disposed in the central area spreads the netting and the slit open to allow unclumped litter to sift through the netting. The clumped litter is retained in the quick sifter and netting material for convenient disposal. The quick sifter is made from a rubberized fabric for reusability.
