Two people in our family are allergic to cats, so we don't allow cats in our house.
Today I opened the kitchendoor to let some fresh air in and went on cleaning one of the cupboards.
Suddenly I felt something was not right and I turned around, seeing a cat almost beside me. She was not looking at me, but completely absorbed in tiptoeing into our house, heading towards the livingroom.
She had the fright of her life when I suddenly told her to leave.
I bet it took her more time to come in than to leave. :)
