  • 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).

  • An FHO, or femoral head ostectomy, is a surgical procedure that aims to restore pain-free mobility to a diseased or damaged hip by removing the head and neck of the femur (the long leg bone or thighbone). This procedure is commonly recommended for cats, especially those who are at a healthy weight. Active cats often experience better results with FHO than less-active cats. It is important to follow your veterinarian's post-operative instructions. Most cats will show signs of complete recovery approximately six weeks post-operatively.

  • An FHO, or femoral head ostectomy, is a surgical procedure that aims to restore pain-free mobility to a diseased or damaged hip by removing the head and neck of the femur (the long leg bone or thighbone). This procedure is commonly recommended for smaller dogs, especially those who are at a healthy weight. Active dogs often experience better results with FHO than less-active dogs. It is important to follow your veterinarian's post-operative instructions. Most dogs will show signs of complete recovery approximately six weeks post-operatively.

  • Fenbendazole (brand names Panacur®, Safe-Guard®) is a medication used to treat a variety of parasites in dogs. Its use in cats for the treatment of parasites is off label or extra label. Fenbendazole comes as oral granules or as a liquid suspension and is given by mouth. At regular doses, fenbendazole does not usually cause any side effects. Fenbendazole should not be used in puppies younger than six weeks of age or in sick animals.

  • Fenofibrate is a fibric acid derivative used as an anti-lipemic agent to lower triglycerides (a type of fat or lipid) in dogs. Its use in cats and other animals has not been studied. It is used off label (extra label) in veterinary medicine. Fenofibrate comes in capsule and tablet forms.

  • Fentanyl is an opioid medication used off-label to treat pain in cats and dogs. It is often given as an injection in hospital, but patches may be prescribed to deliver fentanyl transdermally (through the skin) for pets at home. This handout describes common side effects, risk factors, and drug interactions. If a negative reaction occurs, please call your veterinary office.

  • Ferrets are commonly affected by ear mite infestations. Many ferrets show no symptoms of infestation but you may notice your ferret shaking her head or scratching herself. Treatment for ear mites must be done under the guidance of a veterinarian familiar with ferrets.

  • Due to their well-deserved reputation as escape artists, ferrets should be housed in a cage that can be securely closed and/or locked. They also need a safe, "ferret-proofed" play area or room where they can explore and investigate while supervised.
