Abstract: <P>PROBLEM TO BE SOLVED: To make a litter box for a pet washed by water, by mounting the toilet on a toilet bowl for a human, after solving such a problem that many of the toilets exclusively used by the pet, filled with artificial sand, etc., and used outdoors are troublesome, because the pet has a habit of covering its excrement with the soil, etc, when the pet eases nature, and therefore cleaning of the toilet for somewhat removing odors takes time and effort.  <P>SOLUTION: This litter box 2 for the pet is formed into such a structure as to be set on the toilet bowl 1 for the human. The litter box 2 has a rather larger hole in its rear part to make excrement of the pet drop into a water hole of the bowl 1. The litter box 2 formed into such a shape as to be hollow all over the areas but not including the periphery, because a position from which urine of the pet is passed is variously changed. The litter box 2 is mounted on the toilet bowl 1 for the human and removed away when the human uses the bowl 1. Further, the toilet has a heat sensor switch 3 for sensing weight and heat of the pet, so that the bowl 1 is washed with water, after the pet eases nature and then leaves the bowl 1. Thus, the toilet is kept clean, even when used by both the human and the pet, by remaining the toilet as it is in the bowl, and then showering and washing the toilet, after the pet eases nature, so that the toilet becomes free from troublesomeness.  <P>COPYRIGHT: (C)2004,JPO
