In-Depth Information
A few species of animals are more likely to carry rabies than others.
Always use caution if you come in contact with bats, skunks or rac-
coons (especially during the day, since these are normally nocturnal ani-
mals), because they are common carriers.These animals can carry rabies
but not develop clinical signs.
The rabies vaccine can be administered to kittens over 12 weeks of
age, one year later and then every three years, according to the AAFP
recommendations. However, the frequency of vaccination may be
governed by state and local laws. Certain states require cats to be
vaccinated against rabies, while others do not. Each locale may also have
different rules regarding quarantine of animals who bite humans.
Healthy, nonvaccinated animals who bite humans may be under obser-
vational quarantine for 10 or more days.
NON-CORE VACCINES
The decision to vaccinate with one or more of the non-core vaccines
should be based on the previously discussed risk factors. Non-core vac-
cines are not necessary for all animals. They should be considered for
those cats who have a risk of exposure to the particular disease. You
should discuss the pros and cons of vaccination with your veterinarian.
Chlamydia
Chlamydia felis
is a bacterial infection that causes upper respiratory dis-
ease in cats. Transmission is through direct cat-to-cat contact. The most
common clinical sign is severe conjunctivitis.Vaccination does not pre-
vent infection with chlamydia, but it can lessen the associated clinical
signs.
Don't be alarmed when you hear about feline chlamydiosis caused
by
Chlamydia felis
. This is not the same agent that causes venereal dis-
ease in humans—that bacteria is
Chlamydia trachomatis
.
The prevalence of
Chlamydia felis
in the United States is considered
to be low. Some veterinarians believe vaccines for chlamydiosis produce
a relatively high adverse reaction rate. Chlamydia is commonly the
fourth component of a four-way booster vaccine (FRCPC—Feline
rhinotracheitis, calici, panleukopenia and chlamydia), so be sure to ask
your veterinarian what she is giving your cat.
The AAFP report says that because this upper respiratory disease is
not severe and most cats can be treated, and because the adverse events
associated with the use of the vaccine are relatively high, its routine use
is not recommended. At this time, the duration of immunity conferred
