Microchip cat flap - not finding chip on one of the cats

[HawkeyeInConfusion]

That's it really. I have two rescue cats. Both microchipped. And a microchip cat flap. As we are now being visited by a neighbouring cat I have been trying to set up the flap. It registered one of the cats with no problem. But is not picking up the other one.

Googling suggests that chip failure is quite rare (is it?). But other than taking her to the vets to see whether they can locate it, does anyone have any suggestions please? Thanks.

The only way to check is by someone scanning her.

The chip in one of my rescue cats failed. It was picked up correctly as a little kitten when checked but never found again after that.

Is it a faulty cat flap? We had to send two of them back as the flap wouldn't work. Ring up the customer service they're quite good

Sometimes chips work their way out of the skin. It's happened to one of mine and isn't that uncommon. And there are some types of chips that the flaps don't recognise. However if both cats are from the same place then they are likely to be the same type of chips.

You need to get the cat scanned. I would do that before deciding that the flap isn't working.

Thanks for the replies.

The fact it is working for one suggests to me that it isn't the flap (although I have not ruled it out entirely). And both cats were chipped by the same place (cats protection).

I can't feel the chip under the skin anywhere. But she is quite fluffy, and understandably gets grumpy if I try for too long.

Sounds like a trip to the vets is in order.

I got the cat scanned at the vet. They had no trouble locating it. So it seems that the chip is ok.

But the cat flap still isn't finding it.

I spoke to the cat flap company. They are as baffled as I am.

I'm desperately hoping someone here has encountered similar and can pass on their wisdom.

Isn't the cat flap company replacing the cat flap?.

They didn't suggest it.

I assume that, as it works for one of the cats, it's not the flap that's at fault?

So cats do not put their head further enough into the flap initially, it takes them practice and they need to get used to the click. It took the tail less wonder a month of the flap being propped open to be able to use it properly.

It still might be faulty, it might not be able to read more than one chip. I'd be pushing for a replacement especially seeing as we had two that were faulty so clearly it happens.

Did you get this sorted. Found this thread on Google and we having the same issue

I got a microchip catflap a few months back. I managed to register the little fella prior to installation, but the big fella was a challenge. He wouldn't pass through the flap before it was installed, as recommended, and when it was installed, he wouldn't pass through it slowly enough to register his chip. Over the week and a half, I was literally on my knees coaxing him to come through slowly. I finally managed to catch him when I knew he was really keen to be inside. I was inside and sort of put my hand in front of his head whilst he was entering, to slow him down and it worked! It was a bit of a nightmare because of having to get it into programme mode, but I was determined!

Hope that makes sense & helps.

I had this with one of mine and managed to get it to work by putting a paving stone (small one) in front of the cat flap, which meant that her upper body was much closer to the porch area of the chip. This worked. Huge trip hazard for the humans, but great for the cat!

Thanks for the replies. It turns out her microchip had disappeared. New one in now
