Right folks, I just got a reply from Jackie Haliburton, who is the artist who runs Angel.
"I love to paint cats on shirts ,I can work from photos .....my other email is jackiehaliburton[at]hotmail.com email photos are fine...thanks...Jackie Haliburton"
The price she has quoted me for a large size (to wear in a shift-dress-like way) is 69.00 Canadian $ plus shipping. There are two Canadian dollars to the £ so that means for about £35 plus postage you can walk around in a unique work of art
I'm definitely going to order one.
