Cat Rx Oral Flea Prevention

Fleas can be a major problem for pets and their owners. Even if pets never leave the house, they can be exposed to these blood-sucking parasites. It is not unusual for a cat to become infected with multiple types of external and internal parasites in their lifetime. Preventing flea and parasite infestations is the best protection against them.

Cats must be seen by a 1st Care veterinarian at one of our clinics for a $25 Basic Rx Exam* (find out below how to get the exam for FREE)  once a year to pick up prescription parasite control, unless you wish to obtain a refill for the same prescription product already obtained at a 1st Care clinic within a year. For prescription refills you must bring your original yellow 1st Care certificate (NOT the product box or envelope) to the scheduled clinic. Authorized prescription refills can also be purchased at our Administration office on Thursdays and Fridays with proof of pet’s previous prescription at 1st Care clinic within a year. Please call us ahead to arrange for this refill service. Click on Contact Us for more information.
