Cinnamon Ferrets and other breeds of ferrets are susceptible to heartworm disease in much the same way as dogs and cats. Heartworms can be up to a foot-long and are capable of invading the heart, lungs and blood vessels of your Cinnamon Ferret. Unlike dogs, a single heartworm can cause severe damage to ferrets. Thankfully, there is a heartworm prevention program available for ferrets similar to the program available to dogs and cats. Talk to your vet about placing your ferret on a prevention program. Your vet will most likely conduct a blood test first to verify that your ferret is free of heartworms. He will then start your ferret on monthly oral medication to prevent heartworms. The best form of protection is prevention. Call fellow ferret owners as well as your vet Las Vegas, NV to learn about other ways that you can protect your Cinnamon Ferret from heartworms.
