Our cat loses his regular collar with attached magnet in his brawls. Get replacement is difficult; not many shops have spare magnets available. These magnets in mice form can be attached to each cat collar (completely independent of the thickness and width as well as the closure of the collar). Also, the comfort - it seems - very good. It expresses nothing at the throat / neck of the cat and they accepted of wearing the collar with magnet. Even our cat has no problem to open with this magnet the Staywell cat flap. The only downside: a phone number, name, etc. can not be attached to the magnet.
