Some of you will share my frustration with cats refusing to use their microchip cat flaps. We put ours in last spring and spent all summer and autumn trying to get the three little minxes to actually use it. It goes through the wall, so it's a tunnel rather than a simple flap, and took my husband a LOT of effort to put in.
Despite cajoling, treats, holding it open, picking them up and trying to shove through (not recommended) they would not get the idea of pushing with their heads and resolutely would not even TRY to come back in. After Lara escaped at 10pm by prizing the LOCKED cover up with two sets of claws and squeezing her head UNDERNEATH in an act of supreme contortion, we gave up and locked up for the winter. The kitchen bin in front of it succeeded in thwarting Lara's escape attempts (they're not allowed out at night).
So - imagine my shock. Just over a week ago I'm in the bathroom when I hear all sorts of clicking, bashing and scraping noises. As Sophie is the only one in the house I'm thinking she must have got herself stuck on something. I emerge to find that JESSIE (our nutty ex-feral, but probably the smartest in the pack in her own way) has come in through the locked door. How? She has come THROUGH the cat flap, despite it being locked, and having successfully pushed a very heavy swing bin OUT OF THE WAY with her head!!!
She's now happily trotting in and out of the flap. Lara has followed her out, but not tried to get back in yet.
So there is hope, guys, when you can't get your cats to use it! After several months my little pickle decides she knows exactly what to do with it, and when it's locked and barricaded!

You've got to love them...
