Abstract
A threshold for a covered cat litter box having a side entry comprises a stand supporting an elevated cat landing field. A ramp having a rough litter-dislodging surface extends downwardly from the cat landing field. A barrier is provided for barring cats from jumping onto or off the sides of said ramp. Upon setting the threshold with the ramp accessible to the litter box entry cats may ingress and egress the liter box only via the threshold rough, liter dislodging ramp and landing field which dislodges litter from the paws.
