My cat has perfected the wtf look

[dingit]

Dh has been trying to install a microchip cat flap. Before he fixed it to the wall he tried to get her to walk through it. She gave him the perfect wtf look and wallked through the hole in the wall, even though the back door was open

Oh yes, you've had it once they learn that look.

Cats talk with their eyes.

Argh! She still won't come through when we set the microchip as it makes a clicking noise. Anyone else succeeded with one of these?
