🩺 Health Issues to Be Aware of with Your Devon Rex

Like all cat breeds, Devon Rex cats can be prone to certain health conditions. Being informed helps you care for your companion with confidence and catch issues early.

Here are some of the more common health concerns found in the breed:

💓 Hypertrophic Cardiomyopathy (HCM)

This is the most common heart condition in cats. It causes the walls of the heart to thicken, making it harder for the heart to pump blood effectively.

  • 🩻 Diagnosis: HCM can only be confirmed with an echocardiogram (heart ultrasound).

  • 🐾 Some cats show symptoms (like lethargy or rapid breathing), while others don’t show signs until the disease is advanced.

🦴 Patellar Luxation

This is a hereditary issue where the kneecap slips out of place. In mild cases, it pops back on its own. In more severe cases, it can dislocate frequently or even remain out of place.

  • ⚠️ Severe forms may require surgical correction.

  • 🐱 Affected cats might show signs like limping or “skipping” movements.

💪 Congenital Myasthenic Syndrome (CMS)

CMS causes muscle weakness, often first noticed between 3 and 23 weeks of age. Symptoms can range from mild to severe and often become more noticeable after activity or stress.

  • 🧬 There is a DNA test available to identify this condition.

  • 🐾 Watch for fatigue, wobbly walking, or trouble standing after play.

🧫 Polycystic Kidney Disease (PKD-1)

PKD is an inherited condition where fluid-filled cysts develop on the kidneys. Over time, this can lead to kidney failure.

  • 🧪 A simple DNA test can determine if a cat carries the gene.

  • 💧 Keep an eye on water consumption, appetite, and energy levels—these can be signs of kidney issues.

🦠 Feline Leukemia Virus (FeLV)

FeLV is a contagious virus passed between cats, often through saliva or shared bowls.

  • 😿 It weakens the immune system, making cats more prone to other infections.

  • 💉 Testing and vaccinations are recommended, especially in multi-cat households.

🧬 Feline Immunodeficiency Virus (FIV)

FIV is usually spread through bite wounds. It affects a cat’s immune system and can make them vulnerable to secondary illnesses.

  • 🐱 FIV-positive cats can live long lives with proper care and regular vet checkups.

  • 🛑 Best to keep FIV-positive cats indoors to avoid spreading the virus.

😿 Feline Herpesvirus (FHV)

One of the most common causes of upper respiratory infections in cats. It’s highly contagious and often picked up from other cats.

  • Symptoms include sneezing, eye discharge, and congestion.

  • Once infected, the virus often remains dormant and can flare up during times of stress.

✅ What You Can Do

  • Schedule regular vet checkups.

  • Ask your vet about DNA testing for inherited conditions like PKD and CMS.

  • Monitor for any signs of illness—early intervention is key.

  • Keep vaccinations and parasite prevention up to date.
