Rabies is caused by an RNA virus transmitted through direct contact with infected mammals (primarily bite wounds). The rabies virus attacks the brain and is most often fatal. More cats than dogs are diagnosed with rabies infection in the U.S. If a cat is due for rabies or if this is the first vaccine, the animal is not considered fully immunized for 29 days.

The rabies vaccine should be boostered within one year following the initial rabies vaccination. Once this second rabies vaccine has been administered, cats should receive rabies vaccines on an annual basis unless regulations in the community demand otherwise.


Bordetella is transmitted through airborne pathogens, saliva, and respiratory secretions such as sneezing and coughing. It is a significant and increasingly troublesome pathogen in animal shelters housing large numbers of cats. Symptoms in infected cats rang from mild upper respiratory signs to severe pulmonary and systemic signs. In severe cases, or when left untreated, the virus can turn into broncheophenmonia which could potentially lead to death; especially in young kittens.

Kittens should receive their first Bordetella vaccination when they are eight-weeks-old with a second vaccination at 13 weeks of age. After the first the year, it is recommended to administer a booster every 6 to 12 months; especially if they are in frequent contact with other cats.


FeLV, or The Feline Leukemia Virus, is considered to be the number 1 cause of serious illnesses and deaths in domestic cats. The disease can be transmitted among cats through a number of ways including: casual contact with saliva, mucus, urine, feces, and blood. Other forms of transmissions include passing from mother to kitten, mutual grooming, and fighting. Experimental data demonstrates that young kittens younger than 16 weeks of age, are highly susceptible to the infection.

FeLV causes a cat’s immune system to breakdown, causing it to become highly susceptible to other serious diseases which it would normally be able to fight off. Once the virus enters the body, it will begin reproducing in your cat’s main system of immunological defense- their lymph tissue. From here, the virus will make its way to the bone marrow, interrupting the production of red and white blood cells and breaking down vital components of their immune system. Feline Leukemia Virus is specific to cats and cannot be transmitted to other species such as dogs or humans.

After your kitten receives its initial series of vaccinations during the first year, the Feline Leukemia Vaccine should be administered once a year. In addition to yearly vaccinations, routine testing for the virus is the best way to prevent transmission.


FVRCP stands for Feline Viral Rhinotracheitis, Calicivirus Infection, Calicivirus Infection. The FVRCP vaccine contains three preventative agents: Rhinotracheitis, Caliciviruses, and Panleukopenia.

Feline Viral Rhinotracheitis (FVR) and Feline Calicivirus (FVC) are extremely contagious airborne upper respiratory infections. FVR is caused by the type 1 feline herpes-virus. Both FVR and FVC are chronic diseases that are most debilitating for young kittens and senior cats. Signs include: lethargy, sneezing, coughing, discharge from the nostrils and the eyes, and fever. The virus can turn into pneumonia and occasionally eye ulcers. FCV may also be shed in the feces. Transmission occurs through sneezed macrodroplets, direct from cat to cat, or via contaminated fomites (hands, feeding bowls, etc.). Although the disease is rarely fatal in adult cats, young kittens may develop severe symptoms of this disease which can lead to death.
