This is what Chiarenza says about the piece
Made by George Davidson, it is shown as No. 26 in a circa 1885 catalog. See O. N., X:4, Sept 1995, pp. 6-7 for a fuller discussion and reprints of sketches from the Davison catalog, including the matching creamer.
Known to us only in a chalky white. Height overall 5 1/2"; the base alone is 3 3/4" high and 4 1/2" wide. Rare.
O.N. stand for Opaque News - the quaterly publication of the National Milk Glass Collectors Society
I don't know when they say only known to them in chalky white, if they mean the only milk glass color or if they mean the only color of glass
Edite to add: Chiarenza calls it Dog and Cat, not Cat and Dog.
