Cat Mate Cat Collar Magnets for Electromagnetic Doors, 2-pack

Made specifically for the Cat Mate Electromagnetic Flap Door, these cat collar magnets allow your kitty to unlock the electromagnetic door to enter and exit your home as he pleases—while ensuring that no other strange critters can unlock the door and crawl in! Each pack comes with two magnets, which is great for households with multiple cats, or even serves as a spare if the original tag is lost. And it doubles as an identification tag with a convenient space to write your pet's name and your contact information.
