Fleas are nasty little critters. They suck your cat's blood, which can lead to anemia [source: Miller]. Fleas are also pretty prolific, spreading from pet to pet, and from pet to carpets and furniture. This kind of propagation can lead to allergies and other health problems. Fleas can be especially dangerous to kittens -- the anemia could kill them.
Keeping in mind that more fleas infest the home than the pet, here's how to make your cat flea-free:
- Vacuum everywhere in your house, including the baseboards, beneath furniture and beds, carpets and rugs, corners, crevices, floors and your pet's bed. Be thorough; although you won't necessarily see them, the fleas are there. A side benefit of vacuuming is that the vibrations stimulate fleas to leave their cocoons, so that they'll be exposed to the next step: insecticide.
- Choose a good insecticide containing Insect Growth Regulator (IGR). Check the label to ensure that it is meant to kill adult fleas, eggs and larvae. Spray all the places you vacuumed, as well as on soft furniture and wherever the cat sleeps. Also spray dark areas, where fleas tend to hide.
- Spray insecticide in your yard and garden, where your cat sleeps, as well as in crevices and corners, on gravel and sand, on patios and under the house (if feasible). Focus on the dark areas [source: drsfostersmith].
- Apply a good top-spot flea killer, like Frontline, between the cat's shoulder blades and allow it to disperse.
Be prepared to spray again at the first sign of trouble.
