It holds your FRED tracker in a snap-in silicone case that sits flat and silent, with no jingle and nothing for your cat to catch a claw on. The soft, slim collar suits necks from 19 to 32cm and weighs next to nothing, so kittens and adults barely notice it's there. Tracker sold separately. Why you'll love it Chew-proof and silent. The snap-in silicone case keeps your Fred Go or Fred Pro quiet, protected and firmly in place. Light as a whisker. At around 10g with a slim 1cm-wide strap, it suits kittens and adult cats alike.
