1. A pet toilet, comprising:
a drum, wherein the drum is provided with a first opening and a first accommodating space; the first opening is in communication with the first accommodating space, and the first accommodating space is configured to accommodate excrement of a pet and pet litter;
a base, wherein the base is configured to support the drum; the base includes a left side wall, a right side wall, and a connecting wall that connects the left side wall to the right side wall; a first support arm is arranged on the left side wall, and a second support arm is arranged on the right side wall; the left side wall has a first end and a second end, and the right side wall has a third end and a fourth end; a first safety notch is formed between the first end of the left side wall and the third end of the right side wall, so as to form an open first safety space between the base and the drum;
an excrement collection box, wherein the excrement collection box is arranged below the base, and the excrement collection box has a second accommodating space and a second opening; the second opening is in communication with the second accommodating space;
a sieve component, wherein the sieve component is connected to the drum; the sieve component and an inner wall of the drum are enclosed to form a third accommodating space; the third accommodating space is adjacent to the first accommodating space; the sieve component is configured to separate the pet litter from the excrement; and
a drive device, wherein the drive device is configured to drive the drum to rotate on the base; when the first opening rotates with the drum from an initial position to a defecation position, the pet litter enters the third accommodating space through the sieve component, and the excrement is stopped outside the third accommodating space; the first opening is aligned with the second opening as the drum rotates, so that the excrement falls into the second accommodating space by an own gravity via the first opening and the second opening; and when the first opening rotates with the drum from the defecation position to the initial position, the pet litter in the third accommodating space passes through the sieve component and falls back into the first accommodating space by the own gravity.
