Title
(EN) IMPROVED LITTER BOX ASSEMBLY AND CLEANING METHOD
(FR) ASSEMBLAGE DE CAISSES A LITIERE AMELIOREES ET TECHNIQUE DE NETTOYAGE
Abstract
(EN)
A pet litter box assembly includes an upper box (22) nested within a lower box (24). Upper box (22) has a floor (30) with multiple openings (56) and a plate (58) slidably attached under the floor (30) which also has multiple openings (60). Plate (58) is slidable between a first position, in which openings (56) in floor (30) are blocked by plate (58), and a second position, in which openings (56) in floor (30) and openings (60) in plate (58) correspond. Plate (58) is moved from the first position to the second position to filter unsoiled litter from upper box (22) into bottom box (24), leaving soiled clumped litter in upper box (22) for dumping. Preferably, boxes (22, 24) are identical, and bottom box (24) with filtered clean litter is reversibly nestable in upper box (22) to become the new upper box.
(FR)
Cet assemblage de caisses à litière pour animaux familiers est constitué d'une caisse supérieure (22) emboîtée dans une caisse inférieure (24). Le fond (30) de la première caisse (22) est percé de plusieurs orifices (56) et une plaque (58), également pourvue de plusieurs orifices (60), est placée sous ce fond (30) de manière à pouvoir coulisser. Cette plaque (58) peut glisser d'une première position, les orifices (56) ménagés dans le fond (30) étant aveuglés par la plaque (58), à une seconde position dans laquelle les orifices (56) du fond (30) et ceux (60) de la plaque (58) se correspondent. On fait passer la plaque (58) de la première à la seconde position pour filtrer la litière non souillée de la caisse supérieure (22) et la transférer dans la caisse inférieure (24) en laissant la litière souillée prise en blocs dans la caisse supérieure (22), litière que l'on évacuera ultérieurement. Les caisses (22, 24) sont, de préférence, identiques et celle du dessous (24), contenant la litière filtrée, peut, à son tour, s'emboîter dans celle du dessus (22) devenant ainsi la nouvelle caisse supérieure.
