Heartworm in cats: prevention and test limits
Edited by MaxTeng · Educational content, not reviewed by a veterinarian ·
Cats can be affected, including indoor cats. Canine tests and treatment cannot simply be transferred to them.
Exposure and symptoms
Mosquitoes can enter homes. Cough, vomiting and breathing changes overlap with other diseases and cannot identify heartworm at home.
Testing needs context
Antigen, antibody and imaging methods have different limitations. A veterinarian interprets them with infection stage, symptoms and history; one negative test is not a universal exclusion.
A feline prevention plan
AHS emphasizes prevention. Do not divide dog medication or apply canine adult-worm treatment. Product, age/weight limits, testing and intervals depend on local approval and veterinary advice.
Prepare records
Bring locations/travel, outdoor access, product names and use dates, missed doses, original test reports and symptoms. Labored breathing or collapse requires immediate veterinary contact.
