A Devon Rex does not escape so much as accompany. This elfin, big-eared breed is devoted, mischievous and almost always within a metre of its favourite person, which means it is present at every door opening, every window adjustment and every delivery. Add a light, athletic body that can flatten through surprising gaps and climb to any opening you own, and escape-proofing for a Devon becomes a project about your household's movements as much as your house's fittings.
Know Your Opponent: Curious, Close and Quick
Devons investigate everything, with their paws, at close range, immediately. A screen that bulges slightly, a window resting on a latch, a door that needs a firm pull: your cat will test all of these in the ordinary course of supervising you, long before it has any intention of leaving. Build your defences assuming the cat is beside you, watching what your hands do, because that is where it will be.
Windows and Screens at Every Height
Fit rigid, pet-resistant screens to every window your Devon can reach, which in practice means every window, since a Devon reaches most of them via furniture. Check that frames sit tight and latches actually engage, and get out of the habit of resting windows on a vent position in rooms your cat uses; a motivated Devon can work a paw into a vent gap and widen it. Move climbing furniture a jump's distance away from any window you do open in summer, or keep those windows closed and use a secured room for airing. Inspect screens seasonally for claw damage at the corners, where this breed works its paws when something interesting is happening outside the glass.
The Front Door Routine Is the Main Defence
Most Devon escapes happen at the front door, at ankle height, in under a second. Institute a household pause: before opening, locate the cat; if it is present, either it goes behind an interior door for thirty seconds or a second person holds the doorway with a foot and an eye on the floor. Brief regular visitors until the pause is automatic for them as well, because a defence that only works when you personally answer the door is not a defence.
Flaps, Balconies and the Gaps You Forgot
If your home has a cat flap, decide its status honestly. A Devon who uses a flap has an exit, whatever the packaging promised about selective entry, and a frightened or determined cat can defeat many locking settings; for a strictly indoor Devon, blanking the flap off is the only complete answer. Balconies need rigid enclosure to the full height your cat can jump, not netting at waist level. Then walk the house for the forgotten gaps: the space under a door a slim Devon can nearly flatten beneath, vents at floor level, the opening when the garage connects to the house.
Give the Inside a Better Offer, and Insure the Rest
Containment works best when the indoors wins on points. Give your Devon the high perches it craves near the family's activity, play that uses its spring and intelligence every day, and the company it is asking for when it shadows you, because a satisfied Devon supervises from a cushion while a bored one supervises from the door handle. Even so, insure the failure: check the collar on that slender neck fits, keep your contact details current and hold a clear photo of your cat's face and markings.
