Fancy Mice –
A fancy mouse is a domesticated form of the house mouse, usually bred as a pet. Fancy mice are also called “feeder mice” when they are sold as frozen food for carnivorous pet animals such as snakes. Fancy mice have also been specially bred for exhibiting, with shows being held internationally.
The term ‘fancy mouse’ is used to describe mice that have been selectively bred for exhibition. They can vary greatly in size, from small pet mice that are approximately 15–17.5 cm (6–7 in) long from nose to the tip of the tail, to show mice that measure 30 cm (12 in) nose to tail. Pet mice weigh about 29–44 g (1.0–1.6 oz) but large show mice can weigh up to 130 g (4.6 oz).
