Abstract

A rake for a cat litter box for collecting clumped litter waste material from within the cat litter box includes a support member. A plurality of tines are connected to the support member. Each of the plurality of tines includes a first section connected to and extending from the support member. Each of the plurality of tines further includes a second section extending generally perpendicularly to the first section. The second section of the tines receives the clumped litter waste material in a receiving area. At least one of the plurality of tines second sections includes an upwardly curved portion, curved toward the support member for defining multiple regions of the tines within the receiving area, such that the clumped litter waste material is contained in the multiple regions when collected from the cat litter box.

Claims (7)

1. A rake for a cat litter box for collecting clumped litter waste material from within the cat litter box, the rake comprising:

a support member;

a plurality of tines, each of said tines having a first end and a second end, said first end being connected to said support member;

each of said plurality of tines including a first section extending vertically from said support member to a generally perpendicular bend and a second section extending generally horizontally from said bend to said second end, said second sections of said plurality of tines disposed for receiving clumped litter waste material in a waste material receiving area; and

at least one of said second sections of said plurality of tines, including an upwardly curved portion, disposed between said bend and said second end and curved toward said support member for defining multiple regions of said second sections of said plurality of tines within said waste material receiving area, such that the clumped litter waste material is contained in said multiple regions when the clumped litter waste material is collected from the cat litter box.

2. The rake of claim 1 wherein one of said second sections of said plurality of tines includes said curved portion, and said tine is centrally disposed among said plurality of tines.

3. The rake of claim 1 wherein one of said first sections of said plurality of tines includes a constraint member for retaining clumped litter waste material within one of said multiple regions of said waste material receiving area.
