Visual searches with bare hands rarely succeed on cats with dense double-coats. Conducting a methodical flea comb inspection provides conclusive physical proof. Choose a metal comb featuring fine, rigid teeth spaced no more than 0.2 millimeters apart. Plastic combs flex too easily, letting parasites slip through the gaps.

Seat your cat on a clean white towel or sheet in a brightly lit room. Keep a shallow bowl filled with warm water and liquid dish soap immediately beside you. Work systematically from the base of the skull downward, pulling the comb close to the skin surface. Focus your passes on the back of the neck, armpits, lower abdomen, and dorsal tailhead. Dip the comb straight into the soapy water after each stroke. The detergent lowers the water's surface tension, instantly trapping and drowning live parasites before they can leap back onto your pet.
