Cats + Infectious Diseases

  • Antibiotic-resistant bacterial infections are bacterial infections that are minimally or no longer responsive to commonly used antibiotics. Although these bacterial infections occur naturally, the frequent and/or inappropriate use of antibiotics accelerates the process. Cats with certain medical conditions may also be predisposed.

  • Atovaquone is given by mouth and is used off-label to treat protozoal infections. Give as directed. Side effects are uncommon but may include stomach upset or skin rash. Do not use in pets that are pregnant. If a negative reaction occurs, contact your veterinarian as soon as possible.

  • Feeding raw food to cats is potentially dangerous to both your cat and to you, according to the Centers for Disease Control and Prevention (CDC), the Center for Veterinary Medicine (CVM), and the US Food and Drug Administration (FDA. With nearly 25% of the raw food samples testing positive for harmful bacteria, the health risks for cats who eat the raw food, as well as for the cat owners who handle the food while preparing it, are real. It is reasonable to conclude that a commercially prepared, conventional, complete and life-stage balanced ration is a better choice.

  • Cats are exposed to botulism by eating raw meat or dead animals containing botulinum toxin produced by Clostridium botulinum. Botulism causes ascending paralysis of the nervous system. Clinical signs are reviewed as well as diagnostic tests and treatment. Prognosis is guarded depending on the amount of toxin ingested and the degree of supportive care available. There is no vaccine.

  • Capillaria is a small internal parasite, often less than half of a centimeter in length. They are closely related to intestinal worms, though they can live in a variety of locations within the body. Capillaria can affect both dogs and cats, although dogs are more frequently affected. Diagnosis can be difficult because the eggs of Capillaria are shed only on an intermittent basis. While the parasite is easily eliminated with a dewormer, your cat may require additional medications to decrease the inflammation associated with the infection.

  • COVID-19 is a viral respiratory disease of humans that was first discovered in late 2019. The illness is caused by the virus SARS-CoV-2, which is a new coronavirus that has not previously been identified in humans. Certain animals can be infected by the COVID-19 virus, but it appears to be infrequent. Dogs and cats seldom show severe clinical illness if infected with COVID-19.

  • Cefpodoxime is a third-generation cephalosporin antibiotic used to treat skin infections in dogs. It is also used off-label in cats and to treat other types of infection. It is given orally in tablet or liquid form. Side effects are uncommon. If a negative reaction occurs, contact your veterinarian.

  • COVID-19 is a disease caused by the coronavirus SARS-CoV-2. Current evidence suggests that person-to-person spread is the main source of infection. While there is evidence of transmission from humans to dogs and cats, it does not appear common. If you suspect that you are ill with COVID-19, you should take the same precautions with your pet as you would with people.

  • Cytauxzoonosis is an often-fatal disease caused by a tick-borne protozoan parasite, typically found in bobcats. It is more commonly seen in the southern United States but is spreading with tick migration. It can cause anorexia, lethargy, respiratory difficulty, anemia, and jaundice. Diagnostic testing, treatment options, and preventives are described in this handout. This disease is not transmissible to dogs or humans.

  • Echinococcosis refers to being infected with a tapeworm of the genus Echinococcus and is primarily a parasite of coyotes and foxes. Infected cats are usually asymptomatic, but in both cats and humans the parasite can cause large cysts to form within the lungs and liver. E.multilocularis is treated with praziquantel and in most cases the prognosis is good.
