Have Cat Questions? Ask a Cat Vet Online.
Hi there!Just to clarify, you have two kitties, only one of which goes outside and besides what you've listed, you have not used any other flea control products, correct?
Ok thanks!Flea infestations can be very very frustrating. Keys to success are:1. Understanding of flea life cycle - fleas can get into the house on animals fur or on our clothes, i.e. a cat doesn't even have to go outside to get fleas; once on the pet, fleas feed, produce eggs which drop off into the floors, furniture, carpets, bedding, rugs, etc., and start producing live fleas. Eggs can take up to 6 months to hatch out new fleas and are very difficult to kill.2. In order to control/eliminate the fleas, all pets in the house must be treated monthly with an effective, good quality preventive medication (see below for info); examples include: Vectra, Frontline, Advantage, Advantix, Revolution. Monthly treatment should be applied all year round in most climates.3. Secondly, the indoor environment must be treated as well in order to kill the immature flea stages (eggs, pupae and larvae), otherwise, they will continue to produce more fleas.4. Even if all of that is done, it may take 3-4 months to get rid of fleas because of how difficult it is to kill flea eggs. Those flea products that have insect growth regulators (see info below) are more effective, because they will make fleas have defective eggs that will have difficulties hatching.Here is a link for more information: http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1575 and more in depth information that should help: http://www.drmichaeldryden.com/fleas/3/fleas
