Screen all breeding stock before mating:
Healthy parents create thriving pups
Maximum 4-5 litters lifetime
4-6 weeks between litters
Can mate year-round
Best quality 2-6 months age
Warning: Post-partum estrus occurs immediately - separate males before birth!
Pup Development:
Female Housing
Can live together harmoniously
Male Housing
Must be housed separately
Communal Nesting
Does co-parent successfully
Weaning Protocol
Separate sexes at 21 days
Social dynamics crucial for colony success and pup survival.

Get Started NowUnderstanding and preventing common health issues ensures successful breeding programs
Frequently develop in older does. Can be benign or malignant. Major cause of death in female mice.
Early detection improves outcomes
Clean environment, reduce stress, proper ventilation prevents flare-ups.
Listen for sneezing, chattering, or labored breathing. Isolate affected mice.
Check for excessive scratching, hair loss, or visible parasites. Highly contagious in colonies.
Prevention through quarantine is key
Waltzing (circling), obesity genes, eye defects in certain color lines. Careful selection prevents spread.
Selective breeding eliminates issues
Your commitment to preventive care and health screening creates stronger, healthier Fancy Mouse colonies. Each generation benefits from your careful selection and management.

Get answers to common questions about breeding Fancy Mouses responsibly
Fancy mice have a gestation period of 19-21 days, typically 20 days. Pregnancy becomes visible around day 13-14. Does can become pregnant immediately after giving birth (postpartum estrus), so separate from bucks before delivery to prevent back-to-back pregnancies which exhaust the doe.
Fancy mice typically have 6-12 pups per litter, though litters can range from 3-14. First-time mothers often have smaller litters (4-6 pups). Larger litters may require culling or fostering to ensure all pups receive adequate nutrition. Pups are born altricial - blind, deaf, and hairless, requiring complete maternal care.
Yes! Female fancy mice are highly social and often do better housed together. They frequently synchronize pregnancies and co-parent, sharing nursing duties and protecting each other's pups. This communal raising often results in better survival rates. However, never house males together as they will fight, especially if females are nearby.
Fancy mice are prone to mammary tumors (especially females), respiratory infections (mycoplasma), and external parasites. Sendai virus can cause breeding failures. Some lines have genetic issues like waltzing (inner ear defects) or obesity. Screen breeding stock carefully and maintain clean environments to minimize disease transmission.
Wean fancy mouse pups at 21-28 days old, with 21 days being standard. Immediately separate males from females as they can breed as early as 5 weeks old. Males must be housed separately or will fight. Females can remain together. Early separation prevents inbreeding and unwanted pregnancies.
While fancy mice can breed every 21 days due to postpartum estrus, this is extremely taxing on does. Responsible breeding allows 4-6 weeks between litters for recovery. Does should have no more than 4-5 litters in their lifetime. Continuous breeding shortens lifespan and increases pup mortality.
Fancy mice come in over 40 standardized colors including black, blue, chocolate, lilac, red, cream, and white. Varieties include self (solid), tan (colored top, tan belly), marked (spotted, banded, variegated), satin (shiny coat), long-haired, rex (curly), hairless, and dumbo-eared. Show quality specimens of rare varieties command higher prices.
Initial costs include breeding stock ($10-$50 per mouse for quality specimens), cages ($30-$60 each), and supplies ($20-$30). Monthly costs include food ($5-$10), bedding ($10-$15), and potential vet care. Pups typically sell for $5-$20 pet quality, $25-$50 for rare colors/show quality. Large litters provide modest profits.
Fancy mice are domesticated descendants of house mice (Mus musculus) selectively bred for over 100 years. They're larger, calmer, come in many colors/patterns, and have better temperaments than wild mice. They're disease-free when bred properly, live longer in captivity, and make excellent pets. Wild mice should never be kept or bred as pets.
Pregnant does need extra protein (18-20% vs 14-16% normal), constant fresh water, and nesting materials (unscented tissues, hay). Minimize handling after day 14. Provide hiding spots to reduce stress. Keep cage cleaning minimal during late pregnancy and first week after birth. Extra calcium helps with milk production and prevents eclampsia.
