Nicely "mid-sized" cats, adult Devons average six to nine pounds, with males heavier than females. The Devon personality has been aptly described as a cross between a cat, a monkey, and "Dennis the Menace." Devons are highly active, playful and involved with everything. Powerful jumpers, very few spots large enough to hold them will not be explored and occupied. Devons have been found climbing brick fireplaces and perching on top of doors. Although little escapes a Devon's interest, Devons are very people-oriented. Most Devons invite themselves along for every activity -- preferably perched on a shoulder, lap, or wherever they can be closest to their people

While an even, full coat of loose curls is ideal for the show ring, the Devon coat varies greatly between individuals, ranging from an almost shaggy mop of loose curls in some to a thin suede-like coat in others that may leave some areas nearly bare. The coat may vary over the life of the cat, with some kittens dropping much of their coat ("molting") during their development, and some adult coats changing seasonally. Even though their body temperature is the same as other cats, many Devons are surprisingly warm to the touch due to a lighter, less insulating coat. Not surprisingly, Devons tend to be "heat seekers," and are often found lounging on televisions, computer monitors and heater vents. On chilly nights, Devons make superb bed warmers, often sneaking under the covers to stay warm and share body heat with their favorite people.
