Hi,

Just in case so passing on something that has recently come to light- if new kitty or adding additional to household and with intention for kitty to use flap- check first with pet porte microchip number is compatible before you get the vet and or other to ID micro chip.

Best to call company 01481 265359 as they can verify immediately. The websites are not always accurate and can contradict.

The Biotherm one seems to be temperamental, some work, some don't. As a rule, 9851410 don't work

At least in this way, could save some expense if you select a compatible ID chip.

Company are in the process of looking into this and also 'select exit' where you can program one cat out, one cat stay in

Hope this helps,
