Yes, even indoor cats can get heartworm. While less common than in dogs, mosquitoes, which can easily enter homes, transmit heartworm larvae. A single mosquito bite is enough to infect a cat. The disease manifests differently in cats than in dogs and can be very serious, often leading to sudden death. Diagnosis can be challenging, and there is no approved treatment for feline heartworm disease, making prevention critical. Most veterinarians recommend year-round monthly heartworm prevention for all cats, indoor and outdoor, as part of their routine healthcare. Discuss the best preventative for your cat with your veterinarian. Speak to Dial A Vet via a video consult should you need further guidance.
