According to the May, 2004 issue of Pet Age, based on a study done by
the Centers for Disease Control and Prevention, although dogs and cats
can be infected with the West Nile Virus, they usually do not show clinical
signs of the disease. It seems as though dogs do not develop enough
of the virus to transmit it to mosquitoes, preventing them from being
carriers of the disease. Cats, on the other hand, do develop higher
levels of the disease in their bloodstream. It is unclear if they would
be able to infect mosquitoes.
Although
the study indicated that no dogs showed signs of the disease, some of
the cats did lose their appetite, were lethargic, and had fevers. Therefore,
it is a good idea to check with your veterinarian to determine what
method is best to prevent your dog or cat from being bitten by mosquitoes.
Do not use repellents designed for humans -they may not be safe for
pets.
Be
sure to watch your pet carefully for signs of excessive scratching.
Mosquito bites will cause your pet to itch the same as it does humans.
You
should try to avoid taking your pet outside during peak mosquito feeding
periods (usually dusk and dawn). Never leave your dog or cat outside
all day or all night.
