The Rarity of Lyme Disease in Cats: Explaining the Reasons


As a pet owner, you may have wondered why cats seldom contract Lyme disease, unlike dogs and humans. This illness, caused by the bacterium Borrelia burgdorferi, seriously threatens many animals, but cats are significantly less susceptible. Understanding these reasons can enhance your ability to care for your cat and appreciate their distinctive biology and behaviors.

Natural Groomers – One of the primary reasons cats are less likely to get Lyme disease is their meticulous grooming habits. Cats spend a significant portion of their day grooming themselves, which includes removing debris and parasites like ticks. This constant grooming often leads to removing ticks before they have a chance to transmit the Lyme disease bacterium.

Lower Exposure – Cats, particularly indoor cats, are less exposed to tick-infested environments than dogs. Dogs are likelier to roam in areas with prevalent ticks, such as tall grasses, wooded areas, and parks. In contrast, cats are more likely to stay closer to home and may have limited access to such environments, reducing their risk of tick bites.

Immune System Differences – The feline immune system may also play a role in the lower incidence of Lyme disease. Studies suggest cats have a different immune response to *Borrelia burgdorferi* compared to dogs and humans. This difference may help cats fend off the bacterium more effectively, preventing disease establishment.

Tick Preferences – Ticks have host preferences, and certain ticks are likelier to bite dogs and humans than cats. While ticks can still bite cats, the species most efficiently transmitting Lyme disease may not prefer cats as hosts. This preference reduces the likelihood of cats being bitten by ticks that carry *Borrelia burgdorferi*.

Symptoms Often Go Unnoticed – Even when cats are infected with the Lyme disease bacterium, they often do not show symptoms. This asymptomatic nature means the disease goes unnoticed and unreported more frequently in cats than dogs or humans. The absence of noticeable symptoms does not mean cats are immune; instead, they handle the infection differently.

Prevention is Still Key – While the risk of Lyme disease in cats is low, prevention is still important, especially for outdoor cats. Here are some tips to keep your cat safe:

1. Tick Prevention Products: Use veterinarian-recommended tick prevention treatments for cats. These can include topical treatments, collars, or oral medications.

2. Regular Grooming Checks: Regularly check your cat for ticks, mainly after they’ve been outside. Focus on areas like the neck and ears, and between the ticks may hide.

3. Environmental Management: Maintain a tick-free yard by keeping grass short and removing leaf litter where ticks thrive. Creating a tick-safe zone can significantly reduce the risk of tick bites.

4. Stay Informed: Keep up with regular veterinary check-ups and stay informed about tick prevalence in your area. Your veterinarian can provide the best advice tailored to your cat’s cat’s style and risk factors.
