Abstract: Provided in the present application are a composition for detecting occult blood in excreta, and a preparation method therefor and the use thereof. The composition comprises, in parts by weight, 20-80 parts of organic solvent, 0.01-50 parts of thickener, 0.01-2 parts of benzidine, 0.01-5 parts of peroxide, 0.001-0.5 parts of EDTA-2Na and 10-80 parts of water. The composition provided in the present application can quickly and effectively detect the occult blood condition of excreta, has fast color change, long color retention time and high sensitivity.

Abstract: Provided is a pet cat excrement screening device. The pet cat excrement screening device includes a support base; a drum rotatably mounted on the support base; and a drum driving device mounted on the support base. The drum is configured to rotate between a first position and a second position under drive of the drum driving device, where the rotation angle of the drum is less than 360 degrees. A side wall of the drum body of the drum is provided with a pet inlet. The pet inlet is exposed out of the support base during a rolling process of the drum. A screening mechanism is mounted in the drum. The rear end of the drum is provided with a waste discharge port.
