One rat, one rabbit, one guinea pig, one hamster, one mouse, one gerbil, one chinchilla, one degu and one ferret, each shown four ways: a portrait, a snack, a nap and a hello. They are studio-style portraits edited from public-domain photographs, so each animal keeps its true shape, coat and colouring.
Under the nine are twelve breed portraits made the same way: six rabbits, three guinea pigs and three hamsters. Each one links to that breed's page. The Netherland Dwarf shown is a youngster, and the Angora is a French Angora, one of several Angora breeds.
How to tell them apart
Rat or mouse: a mouse is far smaller, with large thin ears for its head and a pointed nose. A rat is sturdier, with a blunt muzzle.
Hamster or gerbil: a hamster has a short stub of a tail and a round body. A gerbil is slim, with a long furry tail and long back feet. See hamster or gerbil.
Gerbil or degu: a degu is bigger and brown, and its thin tail ends in a dark tuft.
Chinchilla: the largest ears, the longest whiskers and the densest coat of the nine.
Guinea pig: stout, short-legged and with no tail you can see.
Ferret: the long one. Ferrets are the only meat-eaters here; the others eat plants, seeds or both.
