Comfortis Flea Control for Cats

Comfortis are beef flavored chewable tablets used for killing fleas found on cats. An effective flea treatment, Comfortis starts attacking adult fleas within 30 minutes of administration and destroys 100% fleas within 4 hours. To be administered on a monthly basis, these tablets kill fleas before they lay eggs. Its adulticidal activity persists throughout the month to reduce flea population and egg production.

How does it work?

Spinosad, the active ingredient in Comfortis is an insecticide with adulticidal properties. It causes hyper excitation of flea nervous system, paralyzes them and kills them. The continuous action of Spinosad results in elimination of new fleas and prevention of re-infestations by slowing down egg production. This way, a once-a-month administration of Comfortis chewable tablet destroys fleas and breaks its life cycle. Regular use of the treatment reduces flea population to a bare minimum.

When can I start Comfortis treatment for my pet?

For best results, start administering Comfortis a month before the flea season and keep giving until the end of the season. For heavily infested places, it is best to give the tablets across the year without interrupting the monthly dosage. If you have more than one pet at home then treat them all with relevant flea treatments.

Should I check with my vet before starting Comfortis treatment?

Vet advice helps in checking your pet’s sensitivity towards the ingredients of the tablet. This will help in preventing any adverse reactions. Take vet’s advice if you are planning to breed your pet. Seek vet advice for pets with a history of seizures and epileptic attacks.

What is the best way to administer Comfortis?

Pets would take this beef flavored tablet as a treat. For best results, give it with food or after the meal. If the kitty resists direct intake of the tablet then mix it with her food. If possible, repeat every month on the same date.

On missing any of the dose, resume the monthly schedule on the day you remember it. Make sure to give the tablet with food or after it.

What are the possible side effects of Comfortis?

Although side effects are very rare, they might occur to hypersensitive pets. Vomiting is a common side effect but has a transient effect with no need of symptomatic treatment. Lethargy, diarrhea, loss of appetite, redness of skin, excessive drooling, increased thirst, cough, hyper activity are other side possible adverse reactions. Veterinarian advice is a must in case the pet shows any side effects.

Can I club Comfortis with other treatments?

Not without the advice of your vet.
