The flea is an insect that sustains itself by feeding on the blood of host animals. These small parasites commonly affect cats and can be eliminated by using some of the very effective flea treatments that are available. Fleas lay eggs that hatch out as larvae and these can be present in the cat's bed and throughout the home so it may be necessary to also treat the environment. Fleas used to be a seasonal problem but in centrally heated homes and mild climates can be present all year round.
