Cytauxzoonosis (Bobcat Fever) Reported in the Area
We want to alert our community that a confirmed case of Cytauxzoonosis (commonly known as bobcat fever) has been reported in the area. This often fatal disease in cats is caused by the parasite Cytauxzoon felis, which is transmitted through tick bites—primarily from the Lone Star tick.
It’s important to clarify that this disease is not spread directly by bobcats. Bobcats are the natural reservoir host, meaning they can carry the parasite without typically becoming ill. When ticks that have fed on infected bobcats bite domestic cats, they can transmit the parasite—often with life-threatening consequences.
While once seen mainly in the southern U.S., Purdue University’s College of Veterinary Medicine has documented increasing cases throughout Indiana in recent years. The disease progresses quickly, and early symptoms can be easy to overlook. Signs to watch for include lethargy, high fever, loss of appetite, pale or yellow gums, and heavy or labored breathing. Cats often decline rapidly and may not survive without immediate treatment.
There is no vaccine, but Cytauxzoonosis is preventable with consistent tick protection. We recommend using veterinary-prescribed products like Bravecto (topical every 8–12 weeks) or Revolution Plus (monthly topical) to protect your cat from ticks, fleas, and other parasites. Keeping cats indoors and doing regular tick checks can also reduce risk.
Even indoor cats are at risk if ticks are brought into the home on clothing, dogs, or other pets. If you notice any of the symptoms above or have questions about prevention, please contact your veterinarian right away.
We’re sharing this information to help raise awareness and keep our community’s pets safe. Early action can save lives—please help spread the word.
