Understanding Guinea Pig Pregnancy
Guinea Pig Gestation Period
Guinea pig pregnancy lasts 59-72 days, with most deliveries occurring around day 65. Unlike many small mammals, guinea pig babies (pups) are born fully developed with fur, open eyes, and the ability to eat solid food.
Signs of Labor
- •Increased activity or restlessness
- •Loss of appetite
- •Stretching and arching of back
- •Blood-tinged discharge
Breeding Considerations
Heat Cycle
Every 15-17 days, no bleeding like other mammals
Litter Size
2-4 pups typically, up to 5 litters per year
Post-Birth
Can become pregnant again within hours of delivery
Safety Tips
Critical: Guinea pig births can be complicated. Many mothers experience difficulties or don't survive. Professional veterinary guidance is essential for safe breeding.
