Comfortis chewable tablets kill fleas and are indicated for the prevention and treatment of flea infestations on Dogs and now also Cats for one month.

Note: The UK doses Comfortis at a higher level than the U.S. therefore the weight in kg indicated on the UK sourced packs will be less than the actual weight when converted to lbs. Simply choose the appropriate Pack Size by your Pet's weight in LBS. and the correct RECOMMENDED U.S. MIN. DOSAGE of Spinosad will be shipped. Upon receipt, verify dosage (mg) indicated on Pack matches the recommended U.S. dosage (mg) for your Pet's weight in LBS.

Comfortis chewable tablets should be given with food for maximum effectiveness. They are readily consumed when offered by hand prior to feeding but may also be given in food or by placing the tablet at the back of the tongue and encouraging the animal to swallow.
Treatment with Comfortis chewable tablets may begin at any time of the year, but should preferably begin one month before fleas become active and continue until the end of the flea season. In areas where fleas are common year-round, continue treatment with Comfortis throughout the year. In order to minimize the likelihood of flea reinfestation, all animals within a household should be treated with an approved flea protection product.

CATS: Minimum dosage is 22.5mg/lb -Monthly 14 Weeks or older & 2lbs. or greater Cats over 24lbs should be administered the appropriate combination
