Choosing a collar for a Selkirk Rex requires consideration of the breed's dense, curly coat. Standard flat collars can mat the fur around the neck if worn continuously, so a breakaway collar with a smooth, rounded inner surface is the best everyday option. Breakaway clasps release under pressure if the collar snags on furniture or branches, preventing choking accidents. The collar should fit snugly enough that two fingers slide between it and the cat's neck, but loosely enough to avoid compressing the curls.
Harnesses are the safer and more comfortable choice for Selkirk Rex cats that will be walked outdoors or transported in unfenced areas. A vest-style harness distributes pressure across the chest and shoulders rather than concentrating it on the neck, which is particularly important for a stocky breed that may pull against the lead. Look for harness designs with adjustable straps at multiple points to accommodate the Selkirk Rex's broad chest and rounded torso.
Leash training a Selkirk Rex is generally a manageable process thanks to the breed's patient and cooperative disposition. A lightweight, four-to-six-foot leash made of nylon or soft cotton provides enough range for exploration without allowing the cat to dart into danger. Retractable leashes are not recommended for cats, as the sudden tension changes can startle them and the thin cord can tangle around legs or objects.
Introducing a harness should be gradual. Allow the cat to wear the harness indoors for short periods over several days before attaching a leash, and reward calm behavior with treats. Once the Selkirk Rex is comfortable walking indoors on leash, short supervised outdoor excursions in a quiet area can begin. Patience during this training phase builds confidence and makes future outings enjoyable for both cat and owner.
