Infectious Diseases

  • Feline leukemia virus (FeLV) is a virus that infects only cats. It depresses the immune system and cats tend to remain infected for life. FeLV vaccines have been available for many years and have been continuously improved upon. They are helpful in preventing infection with FeLV and, therefore, in controlling FeLV-related disease. Your veterinarian can discuss the pros and cons of vaccinating your cat against this disease based on her specific lifestyle and risk of exposure.

  • Feline panleukopenia (FPL), sometimes also called feline distemper, is caused by a virus of the parvovirus family known as feline panleukopenia virus (FPLV). The virus is present in all excretions, particularly the feces, of infected cats. A susceptible cat can be infected by direct contact with an infected cat, or the virus can be transferred via contaminated water, food bowls, or on shoes and clothing. Clinical signs include rough or dry haircoat, dehydration, depression or listlessness, and collapse. If the gastrointestinal tract is affected, vomiting and diarrhea occur frequently. If the cat receives aggressive supportive care through the initial stages of illness, the prognosis for a full recovery is good. Fortunately, excellent vaccines are available and are part of the core feline vaccination program.

  • Feline upper respiratory infection (URI) is one term for a respiratory infection caused by one or more viral or bacterial agents. Synonyms for this condition include feline infectious respiratory disease and feline upper respiratory disease complex (URD).

  • Usually caused by a bite from another cat, fight wound infections can lead to the development of an abscess (a pocket of pus) or cellulitis (pain and swelling in the area of the bite). A cat’s sharp canine teeth can easily puncture the skin of another cat, leaving small, deep, wounds that seal over quickly, so it is important that your cat is seen by a veterinarian for treatment as soon as possible after being bitten.

  • Fleas and ticks can be found worldwide and can live in many climate zones. Prevention is key to avoid infestations and to prevent disease.

  • Giardiasis is an intestinal infection of man and animals caused by a protozoan parasite Giardia intestinalis (also known as Giardia lamblia). Giardia is a simple one-celled parasitic species; it is not a "worm", bacteria or virus. The parasite occurs worldwide and is a common cause of "Traveler's Diarrhea" in people.

  • Heartworms (Dirofilaria immitis) are blood-borne parasites that reside in the heart or nearby large blood vessels of infected animals. Veterinarians now strongly recommend that all cats receive year-round monthly heartworm preventives.

  • There is no drug approved for treating heartworms in cats and surgical removal is generally the best option. Veterinarians now strongly recommend that all cats receive heartworm preventative.

  • Heartworm disease is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis. Adult heartworms may live for five to seven years and, during this time, the female produces millions of offspring called microfilaria. You can prevent your dog from getting heartworms by using a heartworm preventive.

  • Heartworm treatment involves several components to combat potential bacterial infection, kill heartworm larvae (microfilaria), kill adult heartworms, and then test to confirm successful treatment. Complete rest for a dog undergoing treatment is essential.
