Cat sitter in London

I am a creative living in E5 and working in Shoreditch for a human rights charity. I am an avid cat-lover and have grown up with cats my entire life. In my current living space my flatmate has a dog and therefore it would not be wise for me to bring a cat into this space. Therefore, I am looking to get out of the flat and look after some little feline furries! I am not trained to administer medication but I think I am a good buddy to cats in terms of giving them attention when they need attention, playing with them, giving them treats when they are well-behaved, feeding them, but also leaving them alone when they want to be alone. I work full-time between 9am and 5pm so I am free anytime outside of this and at any time on weekends.
