If pet owners want to forego treatment because their kittens or cats remain indoors, remind them that queens can carry parasites
like T. cati, insects and small rodents can carry parasite eggs or larvae indoors, and fleas can develop in some indoor locations. Plus,
veterinarians know that many "indoor" pets are allowed brief periods of time outdoors, where they're exposed to eggs, larvae,
fleas, and heartworm-infected mosquitos.
The CAPC guidelines recommend administering year-round heartworm prevention products with additional broad-spectrum activity
against roundworms, hookworms, and other parasites as early as possible and throughout a pet's life. Several of the products
1 are compatible with this recommendation and can be administered during the first veterinary visit or earlier. Revolution,
Interceptor Flavor Tabs, and HeartGard for Cats have label claims against heartworms, fleas, or both. Additional claims against
T. cati, A. tubaeforme, Ancylostoma
braziliense, or a combination of these parasites are also beneficial. Revolution comes in a topical formulation, providing added convenience
for pet owners.
Other published guidelines for controlling feline parasites and other zoonotic agents include the Guidelines for Veterinarians: Prevention of Zoonotic Transmission of Ascarids and Hookworms of Dogs and Cats, from the CDC's division of parasitic diseases (
http://www.cdc.gov/ncidod/dpd/parasites/ascaris/prevention.htm) and the Feline Zoonoses Guidelines from the
http://www.aafponline.org/about_guidlines.htm). Both contain recommendations similar to the CAPC guidelines.
If you haven't already, take the initiative and implement comprehensive parasite control strategies in your practice today.
By combining proper diagnostic techniques with the appropriate, broad-spectrum control products, you'll prevent parasites
from jeopardizing the health of your feline patients and their owners.
