Litter box rake

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.
