Protect your cat against the dangers of heartworm. By offering heartworm medicines like Heartgard, Interceptor and Revolution, we believe more cats will be able to receive the heartworm protection they need.
Before you place your order, please have your veterinarian provide our pharmacist with your pet's prescription. State and Federal law requires us to have your prescription on file before we can dispense prescription medications. Thank you.

All cats should be tested for heartworm infection before starting a preventive program. In a small percentage of ivermectin/pyrantel treated cats, digestive and neurological side effects may occur.
