Staywell Magnet Mouse Key
These constantly break at the nose where the ring is... Twin packs do help. lets see if this lot will last... Also really hate how the magnet gets filthy with rocks and metal pieces my cats pick up outside. Nails, and bits of metal scare me when they are attached to the cats neck and try to come through the cat door.
In the past these have broken at the mouse 'nose', so I was pleased to see them available in a 2 pack (no collar) at a reasonable price. This pack claims they have a 3 year guarantee, so time will tell!
