My Space: celebrities at home Everything that I've ever created - from The Tiger Who Came to Tea to the Mog books - started life in this studio, upstairs in my house in Barnes, in southwest London. My husband and I lived here for 50 years, though sadly he died recently. When we first moved in, the light in the studio was marvellous. But over the years, the oak trees outside grew and blocked out the sun. So I decided to paint the walls and floor white, which helped a great deal. I still spend most of my time here. For my 90th birthday next year, I am working on an illustrated autobiography which I call All About Me And How Wonderful I Am. I still miss my first cat, Mog. I was a refugee from Nazi Germany as a child and we were too poor to afford a cat, so Mog was like a dream come true. She lived for 19 years and used to nudge the pen with her nose when I was drawing her. But when I was drawing something else, she went and sat in the chair. I don't know how she knew.
