However cat fleas can transmit some diseases. Popular method of flea control for cats are cat flea collars since they are economical-

Cat flea collars functions as flea killers and preventers trough producing toxic gas which kills fleas but doesn’t harm cats. Gas is also absorbed in skin fat layer so it covers larger area than just a neck, which is spot which fleas love the most.
