This is a watercolor painting of Tyne Tyne, a siamese cat that belongs to one of my eBay customers, and his story was so compelling and picture so beautiful, I just had to paint him! This original is still available.

Bookshelf Cat. Books and a black cat. Perfect match. Love both.
Artwork by Lisa Parker, a UK artist (http://www.lisaparker.co.uk/) Probably digital artwork in this case, though she also does oil paintings.
Watercolor Cats by Dani Hasse via Flickr - this is great inspiration for a doodle or tangle pattern
