An indoor Norwegian Forest Cat should wear a breakaway collar carrying both a scannable QR ID and a printed phone number. This is a big, slow-maturing breed with a dense double coat, tufted ears, and a full bushy tail, and size changes the identification problem: a dainty collar made for a small shorthaired cat disappears into that mane, and a finder may lift the fur, see nothing, and assume the cat is unowned.
Make the tag visible through a double coat
Visibility is the first job for a Norwegian Forest Cat's tag. Choose a flat, reasonably wide tag that rests on top of the outer coat rather than sinking between the layers, and use strong contrast so the printed number reads at arm's length. The profile behind the code should describe the features that survive distance: large size, ear tufts, a long plumed tail, and the exact coat colour and pattern, because two Forest Cats in one neighbourhood can look surprisingly alike in a hurried phone photo.
Size the collar for a large, growing cat
Sizing needs revisiting because a Norwegian Forest Cat keeps filling out for years and gains a much thicker winter coat. Fit a breakaway collar so two fingers pass underneath with the coat pressed down, not fluffed up, and test that the clasp releases with a firm tug. Recheck when the seasonal coat comes in and after any change in weight, and replace a collar that has started to mat the fur beneath it, since a hidden sore makes a cat fight wearing identification at all.
Describe temperament so a finder approaches well
The profile should prepare a finder for how this breed behaves with strangers. Many Norwegian Forest Cats are calm and self-possessed but not instantly cuddly with unknown people, so note that the cat may watch from a distance, accept food left nearby, and dislike being grabbed. That single note prevents the common failure where a helpful stranger lunges, the cat bolts across a road, and a findable cat becomes a lost one.
Keep a second record beyond the collar
A second record matters because a strong climber can strip a collar on a fence or branch. Note the identification details with your veterinarian, keep recent photographs that show the tail and ear tufts clearly, and store one full-side picture taken in daylight. If the collar is found without the cat, those photographs let you confirm sightings quickly instead of chasing every large longhaired cat reported nearby.
If this indoor cat gets out
Search high as well as low if your Norwegian Forest Cat slips out, because this breed climbs confidently and may settle on a shed roof, a fence line, or a low branch rather than under a bush. Walk the area after dark with a torch, pause to listen, and ask neighbours to check garages that stood open. A large cat is easier to spot than most, so early, specific descriptions tend to bring reports quickly.
