Your vet may tell you that it’s safe to assume that all cats including your American Wirehair are potentially at risk for heartworms. Heartworms can often be as long as a foot. They are capable of invading the heart, lungs and blood vessels of your American Wirehair. The disease is transmitted through mosquitoes. Some American Wirehair cat owners believe regions of the U.S. are more prone to heartworms than others and may not see a reason to protect their cat. Heartworm disease; however, has been diagnosed in all 50 states. It should be assumed that the risk is present everywhere. The best way to protect your bobtail is to have her tested yearly for heartworms as well as place her on a monthly heartworm preventive program. If you’re not sure if your cat is already on a prevention program, please call your vet. For additional information, please contact your veterinary clinic Las Vegas, NV.
