You can easily distinguish Devon Rex from other breeds of cats because of their slender bodies, wavy coat, and large ears which resulted from a recessive gene. And this is the reason why they need to have a special type of grooming; they have very fragile hair coats that even brushing them gently could cause some breakage.
Another thing is that their skin glands produce oil that covers their hair coats which makes them greasy. The oil is essential in maintaining the healthiness and integrity of their skin and hair coat. Generally, with other cats, these oils are already distributed all over their hair coats making them not look greasy at all. Oil can also accumulate on their skin because of having thin hair coats. This can also cause their nail beds to look greasy.
If not groomed properly, these cats can rub the grease off their body on furniture, beds, etc. Any sign of skin and/or hair coat issue should warrant a visit to your veterinarians San Antonio TX.
