Description

Full-automatic pet cat lavatory

Technical Field

The utility model relates to a pet articles for use technical field, concretely relates to full-automatic pet cat lavatory.

Background

Nowadays, more and more people start to raise pet cats, and the pet cat excretion problem is always troubling the raisers in the process of raising the pet cats. Although pet cats can be discharged at fixed points in the cat toilet without training relative to pet dogs, pet cats still retain the instinct of animals before domestication for the problem of discharge, and cats cannot continue to defecate or randomly defecate everywhere if the excretion in the cat toilet is not cleaned in time. Moreover, cat excrement has strong odor and a large amount of bacterial viruses, which brings health and sanitation troubles to breeders.

Because cats have the physiological habit of digging down cat litter to bury excrement after excretion, all breeders can equip pet cats with a special cat toilet, namely a litter box. Cat litter basin among the prior art includes the basin body and strainer, places the cat litter in the basin body, and the person of raising filters out the excrement of pet cat from the cat litter through the strainer every day to realize the regular cleanness of cat litter. The prior art has the disadvantage that the litter must be manually cleaned daily or the pet cat will not be discharged at a fixed point.
