Abstract: A sterilizing comb for pets includes a case, a plurality of bristles attached on the case and a sterilizer. The sterilizer is a lamp that emits high-energy rays. The high-energy ray may be the ultraviolet ray or the infrared ray. The case includes a body and a handle. The body includes a brush plate and one or more light emitting openings. The bristles are attached on the brush plate. The high-energy rays are emitted through the light emitting openings. The sterilizing comb further includes an air suction fan and a photo catalyst filter. The air suction fan sucks air through the light emitting openings. The photo catalyst filter generates photo oxidation with the high-energy rays. The air suction fan is positioned adjacent the photo catalyst filter so that the sucked air passes through the photo catalyst filter.
