A maintenance schedule for a Devon Rex is simple and easy. They have thin coats, which can become greasy and need regular bathing. A mild shampoo and warm water may do wonders for their beauty and health. They also require regular nail trimming and cleaning of the ears and eyes to avoid clogging. It would be necessary to brush their teeth twice a week; otherwise, plaque may develop.

Another important point is their sensitivity to low temperatures or cold environments, and this is because they have a thin coat. This also makes them a target for sunburn if kept in extreme sunlight for a long time, so don’t let them out in the sun for too long. 

On the other hand, the Cornish Rex is a low-maintenance cat. Its thin coat requires a minimal grooming schedule, and if you overgroom it, you can damage its delicate skin and hair. However, they will require regular nail trimming, ear cleaning, and tooth brushing schedules. They are also sensitive to low temperatures, so do not leave them out for too long in the cold or heat.


Cornish Rex gets full marks for activity level and playfulness. Another important feature is their attraction and attachment to the owner. However, in terms of attitude toward other pets and cats, they don’t mix well. They aren’t very independent, and they need their parents and owners a lot for food and care. 

In contrast, Devon Rex is highly playful, naughty, and active. They are often described as “a monkey in a catsuit.” They love to run here and there, play extreme physical games, and jump to high places. They tend to develop affection for their owners and hang around their shoulders and necks.

They don’t miss the opportunity to hug their owners and follow them wherever they go. Also, they love to play with other pets and do not engage in fights. They also have “clownish” characteristics as they love to entertain people.


Devon Rex is best suited to a home with plenty of toys and playmates. They also crave attention and tend to follow their owners everywhere; they would suit a household where someone is home regularly throughout the day. These cats have a thin coat and must be kept out of severe environmental conditions. 

Cornish Rex cats love to climb and jump, so you must provide cat walls and furniture so they can have fun exploring. In general, both breeds of cats require someone who is home regularly and can play with them every day.

Which cat is right for you? 

Cornish Rex is not hypoallergenic, so if you are looking for a cat and have allergies, you should probably get a Devon Rex. These cats are great entertainers and are usually very energetic. They also get along with other pets and the kids in the house.

On the other hand, if you do not mind a lot of shedding and are free from allergies, the Cornish Rex is a great breed. They can be very playful at times and generally love affection and playing around. However, they do not get along well with other pets.
