Bessie Bamber worked in oils and specialised in painting cats, kittens and occasionally puppies. She usually painted on porcelain or opaline glass, and sometimes on a polished mahogany panel. She preferred to work using stuffed animals rather than live ones. There is no record of her exhibiting her paintings. A picture of three kittens with a pile of books was sold for £2,468 by Bonhams in 2004.
