The base portion has a floor (20) and a raised, peripheral ledge (22) with a vertical wall (28) and a horizontal wall (30). The pet litter box has a removable tray (40). The horizontal wall includes air vents (56). Each air vent has an upwardly extending hood (58) having a rear wall (60), two oppositely disposed end walls (62) which define an outwardly facing air outlet opening (64). Each side air outlet opening is in fluid communication with a bottom air inlet opening (66) extending through the ledge horizontal wall.
