I've been looking for a treatment to eliminate the fleas and ticks off my cat. I looked all over the internet and found a product called comfortis (spinosad) which is designed for cats. Spinosad, which is the active ingredient in Comfortis is made to kill fleas. When adult fleas suck the blood out of your pet it gets comfortis into their system and dies. Effects usually take place withint 30 minutes to 4 hours.

When the fleas eggs hatches all hell breaks loose and now fleas will bite your whole household- it happened to me so it is probbaly better to kill off the fleas when It first starts- that way the fleas don't hide all over your house in the dark areas.
Comfortis does have some side effects so you will have to talk to your veterinarian before making the decision to use this product, albeit I gave it to my pet without any problems. Comfortis flea pill medicine is designed to kill off fleas- and it is taking orally- your cat takes it orally- not you.
So with this the side effects may be nausea, vomitting, lost of appetite- if you notice any behavior changes please talk to your vet before continuing with this flea medication.
Comfortis for cats is really effective from my personal Experience. It is also effective on dogs.
