Standard size 1 inch 25mm

Not cheap, but does the job perfect

Had to get a chip activated cat flap as a local Tom making his presence known. The chip in our two 6 am 8 years old and whilst they still read I wanted belt and braces access to the house for them. Easy programming, fa's easier than yhe darn chips, herding cats is actually a thing BTW and not that much fun for moggie or hunan. So with these programmed and on their collars they come and go as they please. Disk is high quality and just 2mm marker than the name/id disk so mo issues at all. Thoroughly reccomend these for use with chip operated cat flaps.

worked great very happy kitty

The tags worked with the cat flap well, easy to set-up and use. However, the metal rings are too thin and the tags fell off with in a couple weeks of being purchased.

Easy fit cheap and they work

These work great with our cat flap.

They are quality discs which are light in weight and fit nicely on my cats collar allowing her freedom to go in and out safely.

Can’t return has cat has lost the one that did work - check both work when you get them!

Ne fonctionne pas avec ma pet mate, dommage moins gros et plus mignons que les originaux

Works perfect for my Closer Cat Mate door.
