Trusted sources must also allow you to meet the parents of the Devon Rex. A family tree must be readily available in case you ask one from them.

Whether the Devon Rex comes from a good breeder or an adoption center, proper care remains to be a requirement. How you treat your pet will either add up more years or shorten his lifespan.

Give him lots of love and attention to fill up his psychological and emotional needs. A happy cat will be able to dodge most problems that can impact his overall health. 

His physical needs must also be met. As mentioned, this cat has a fondness for playtime. Cat toys will stimulate him both physically and mentally. 

Common Health Problems That Shorten His Lifespan

No cat breed is exempted from having health issues and that includes the Devon Rex. No matter how healthy he was when he was still a kitten or how much you care for him, there is still a likelihood that his body will develop certain diseases or subject him to various types of illnesses.

The common ones are:

Digestive Issues

Digestive issues can be subtle. In some cases, they develop over time. Unsurprisingly, If your Devon Rex has this, certain symptoms may show, and if these are left untreated, likely he won’t be able to have a normal life expectancy. Watch out for these signs and bring him to the vet if any of them are constantly exhibited by your kitty:

  • Constipation
  • Vomiting
  • Diarrhea
  • Decreased appetite
  • Weight loss
  • Dehydration
  • Anorexia


Lymphoma is a systemic disease. You may better understand this as the cancer of the lymphocytes. This can strike your Devon Rex if he has not been vaccinated for feline leukemia. Although most cats no longer suffer from this condition, lymphoma remains to be commonly-seen cancer. Its usual lymphoma sites include:

  • Gastrointestinal tract
  • Lymph nodes or thymus
  • Kidney

Of all cats who are diagnosed with lymphoma, around 75% are successfully treated, although some tend to relapse. They have a median survival time of 6 months, but those who are untreated typically last for 6 weeks only.


Cardiomyopathy is a commonly diagnosed heart disease in cats including the Devon Rex breed. What happens is that the muscular walls of the feline’s heart thickens and hinder it from functioning properly. Sometimes, Cardiomyopathy can also cause more symptoms in various parts of the body such as stunted growth or lethargy. 

If a Devon Rex suffers from moderate heart disease, he can live for years. Unfortunately, its unpredictability may also mean dying without warning. Others may live for about 2 to 18 months.

We only want the best for our cats hence why we should aim that our pets live a healthy lifestyle. Although we cannot control everything, especially that some factors that can shorten his lifespan are persisting, the least we can do is to be responsible and committed to aiding him to become a robust cat that can withstand life’s challenges.

So, what can you do to lengthen his lifespan? Here are 7 habits you should know:

Keep Him Indoors

Cat-proof your house! Moreover, keep your Devon Rex indoors at all times. If he’s outside, unattended, this feline can end up getting hit by a dashing car.


Regular exercise drills improve your Devon Rex’s health. Let him practice his natural hunting skills with the right toys. You may also train him so he’s also mentally stimulated. If these aspects of him are boosted, his overall health gets even better!

Good Food

Never skimp on your Devon Rex’s cat food. Only go for high-quality ones that will provide him sufficient nutrients. If your pet is still a kitten, a kitten-appropriate meal should be provided. Regularly feed him as well to avoid digestive problems. 

Regular Vet Check-up

Veterinarians are the most qualified in determining the health status of your beloved Devon Rex. Bring him to the clinic religiously so if ever something’s wrong, it can be diagnosed and treated at an early stage.

Spay or Neuter

Aside from reducing medical complications, spaying or neutering your Devon Rex will keep him disinterested from roaming outside to mate. Other stray animals carry infectious diseases. If it isn’t the health risk you should be concerned about, it would be catfights that may happen during his escapade. 

Although cats that fight each other do not end up killing the other, physical injuries like wounds and bites can cause untimely death. 

Keeping Yourself Informed
