How Long Do Devon Rex Cats Live?
Devon Rex cats are a unique and lovable breed, known for their playful personalities and distinct, curly coats. If you’re considering adding one to your family, you might be wondering—how long do Devon Rex cats live?
On average, they live between 9 to 15 years, though some can live even longer with proper care.
Let’s dive into what affects their lifespan and how you can help your feline friend live a long, happy life.
Average Lifespan of a Devon Rex
Most Devon Rex cats live between 10 to 15 years. This is comparable to or slightly above the average lifespan of domestic cats. However, individual lifespans vary based on factors like genetics, diet, environment, and overall health.
Some Devon Rex cats have been known to live beyond 15 years, especially when given excellent care and regular veterinary check-ups.
Factors That Influence a Devon Rex’s Lifespan
1. Genetics
Like all purebred cats, Devon Rexes can inherit certain health conditions. Responsible breeding helps reduce the risk of hereditary diseases like cardiomyopathy (a heart condition) or hip dysplasia. If you’re adopting from a breeder, make sure they perform health screenings on their cats.
2. Diet and Nutrition
A high-quality, well-balanced diet is crucial. These cats have fast metabolisms, so they need nutritious food that supports their energy levels. Make sure they get:
- High-protein meals to support muscle health
- Healthy fats for a shiny coat and energy
- Fresh water daily to prevent dehydration
Avoid feeding them too many treats, as obesity can lead to serious health issues.

3. Indoor vs. Outdoor Living
Keeping a Devon Rex indoors can significantly extend their lifespan. Outdoor cats face risks like:
- Predators
- Traffic accidents
- Exposure to toxins or diseases
If you want them to experience the outdoors, consider a cat-proof enclosure or supervised leash walks.
4. Regular Veterinary Care
Routine vet visits help catch potential health issues early. Essential healthcare includes:
- Vaccinations to prevent infections
- Dental care to avoid gum disease
- Spaying/neutering to reduce the risk of reproductive-related diseases
Cats that receive consistent veterinary care often live longer and healthier lives.
Do Male and Female Devon Rex Cats Have Different Lifespans?
Yes! On average, female Devon Rex cats live about two years longer than males. This difference is common in many cat breeds.
Additionally, spayed or neutered cats tend to live longer than those left intact. This is because sterilization reduces the risk of certain cancers and eliminates the dangers of pregnancy-related complications in females.
Life Stages of a Devon Rex
Like all cats, Devon Rexes go through different life stages, each with its own characteristics.
1. Kitten (0–12 months)
- Full of energy and mischief
- Requires frequent meals for growth
- Begins socialization and training
2. Adult (1–8 years)
- Maintains playful personality
- Fully matured physically and emotionally
- Needs regular exercise and mental stimulation
3. Senior (8–15+ years)
- Slows down but stays affectionate
- May need special senior cat food
- Requires more frequent vet check-ups
