PATHOLOGY

Detailed explanation-1: -There is no FDA-approved drug to treat heartworm disease in cats, although symptoms may be managed with medications. Surgical removal of adult heartworms may be a treatment option if the heartworms can be seen by ultrasound.

Detailed explanation-2: -Because of this life cycle, it is necessary for a cat to be bitten by an infected mosquito in order to become infected with heartworms. Heartworms are not transmitted directly from one cat to another or from a dog directly to a cat.

Detailed explanation-3: -Heartworm disease in cats is very different from heartworm disease in dogs. The cat is an atypical host for heartworms, and most worms in cats do not survive to the adult stage. Cats with adult heartworms typically have just one to three worms, and many cats affected by heartworms have no adult worms.
