Do cats get Lyme disease from ticks?

Cats can be bitten by deer ticks and carry the Lyme bacterium, but they appear to be significantly more resistant to developing clinical Lyme disease than dogs are. That said, cats with outdoor access are exposed to ticks and can carry other tick-borne organisms, so tick prevention for outdoor cats is still recommended -- consult your vet for cat-appropriate products.

How quickly can a tick transmit Lyme disease?

For the most well-studied tick-Lyme pathway (deer ticks and Borrelia burgdorferi), research suggests that transmission generally requires the tick to have been attached and actively feeding for at least 24-36 hours. This is why prompt tick removal after outdoor time significantly reduces disease risk -- even if a tick is found, removing it quickly may prevent transmission.

Can I use a dog tick prevention product on my cat?

No -- never apply a tick prevention product labeled for dogs to a cat without explicit cat-safe labeling. Permethrin, which is found in many dog tick prevention products and is safe for dogs, is highly toxic to cats and can cause severe, potentially fatal neurological reactions. Always use products specifically labeled for cats.

Should I get the Lyme disease vaccine for my dog?

The Lyme vaccine is a non-core vaccine -- recommended based on risk rather than for all dogs universally. If you live in or regularly visit an area with established Lyme disease risk, and your dog spends time in tick-prone environments (wooded areas, tall grass, trails), it's worth discussing with your vet. It provides an additional layer of protection alongside tick prevention products.

What should I do if I find an engorged tick on my dog?

Remove the tick promptly using fine-tipped tweezers, grasping as close to the skin as possible and pulling steadily upward. Clean the bite area with alcohol. Note the date of removal and watch your dog for signs of illness (lethargy, fever, joint pain, appetite loss) over the following weeks. If your dog develops any of those signs, or if you have concerns about the tick species or duration of attachment, contact your vet.
