Thank you for viewing! These are soft-furred mice, bred in-house for my pet snakes! I am selling them because production has exceeded consumption. The soft-furred mice are fed dog food and vegetables. These are mice that ball pythons are said to eat in the wild! My snakes at home also eat much better when given soft-furred mice compared to regular mice! They are larger than regular mice and are also called petite rats. Shipping included for an additional 1500 yen. Free shipping for bulk purchases of soft-furred mice over 10,000 yen! I am sorry, but I cannot ship to remote islands because of the limitations of Kuroneko Yamato. Please let me know if you have a preferred delivery time: 8:00 - 12:00 14:00 - 16:00 16:00 - 18:00 18:00 - 20:00 19:00 - 21:00 Instant purchase is OK!
