Feeder mice, which are typically sold as food for other animals such as snakes, are generally less expensive and can cost around $1 to $3 per mouse. However, fancy mice that are bred for show or as pets are usually more expensive due to their specific characteristics and genetics.
Additionally, if you're looking for a specific color, pattern, or variety of fancy mouse, such as a rare or sought-after color mutation, the price may be higher. It's always best to check with local breeders or pet stores for the most accurate pricing information in your area.
