If anyone can solve this mystery which has been plaguing me for months I would be very grateful.
We have one middle aged cat and for years have one of those microchip catflaps which only let recognised cats in. It worked fine, including for our previous (now deceased cat).
Then we got a new cat, who is to remain a house cat. The cat flap lets any cat out so obviously this wouldn't do. We purchased a new 2 way microchip one and programmed it so only the older cat could go in and out.
Apart from she can only come in, she can't get out.
We have tried resetting it so many times and it just doesn't recognize her when she tries to leave. Is fine coming in. DH has a keyfob for work with an rfid chip in so we programmed that to the cat flap and that works in both directions.
I contacted the cat flap company who sent me another rfid chip in a ruler widget to measure how far away the range is and it's 26cm both sides so they say their cat flap is fine. I said it can't be and to shut me up they sent me a new one.
We have exactly the same problem.
I took the cat to the vet to get another chip fitted and vet wouldn't do it. She scanned the cat and the chip shows up fine. Vet says the cat flap must be faulty. But if it was faulty why would it work for 2 X Non cat inserted chips. And why would both flaps have the same issue?
It's been 4 months now since cat could let herself out.
