Check the two optical sensors in the tunnel at the top near the door (outside) are clear and not obscured by cat hair. Also check that the bottom part of the tunnel where the cats belly goes when it comes in is still clean too. If either of these two are a problem then the unit thinks there's a cat in the tunnel and it switches on the microchip reader which uses a lot of battery. We have a long haired cat and the outer part of the flap near the hinge with the draft excluder needs regular cleaning to stop this happening. Good luck
Hi there - I would suggest to replace the batteries - if they are a cheaper brand or have been used at all then it drains them quickly. Duracell work perfectly, change them all at the same time (like you would tyres) :)
Yep. Sounds like you've got a faulty unit. Just check to see if the batteries are fitting nice and snug. I would expect under normal use that the batteries would last about a year ! If not E-Mail the company through Amazon and get another one sent out to you. All the best , Rog.
I have had this catflap for 3 years and it eats batteries: I have to change them every 3-4 weeks. Cleaning the sensors doesn't seem to make much of a difference, and expensive batteries last only marginally longer. This is my only criticism. It does the job brilliantly, with no unwanted visitors.
