What the CDC says

  • Ticks can carry diseases to pets and can ride into your home.
  • Signs of tickborne disease may not appear for 7 to 21 days or longer.
  • Except for Lyme disease in dogs, pets cannot be vaccinated against tickborne diseases.
  • Check pets daily, especially after outdoor time, and remove ticks right away.
  • Cats are extremely sensitive to many chemicals. Ask a vet before using any tick product on a cat.

In a home with cats

The ASPCA warns that permethrin, common in dog flea and tick products, can make cats unsteady and cause tremors or seizures. Read the label and ask your vet.
