Cat sitter in London

I'm a Brazilian student living in London since September. I'm taking my masters degree in KCL and have a lot of free time to spend taking care of cats. Back in Brazil I had 4 cats that meant the world to me. I tried to bring them here but it's really hard to find places that allow pets. Anyway, my mom is taking care of them now and I know they are being taken great care because we Skype every week :)
