Honestly, with some of these places frankly its easier to adopt a baby than it is to adopt a cat. In my own case, they even came to my house to ensure it was suitable. I live in a sizable farm house!. It was a right long process that took weeks, it was ridiculous. I also paid for the jabs and microchip and it was only at a vets check up a year later i discovered he hadn't got a chip and i paid again! The cats league had filled in some paperwork but forgot to chip him.
I absolutely adore cats, you need to stick with it/ call them again but it does make you think twice for next time, which is a shame as these cats need a loving home and fast.
Good luck
