Odd behaviour at the cat flap.
Dory has exhibitted some odd behaviour at our cat flap since the day we put it in. Sometimes, instead of going out, she'll stand on her back legs and rest her front paws on the inside rim of the cat flap. She then holds it down with one paw and relentlessly pings the inner flap housing with her other paw.
She knows she can go out - the flap is unlocked, but it can get quite annoying if she does it at night.
Anyone else seen this behaviour or know what it might be ?
