Are baby guinea pigs called kits?

Yes, baby guinea pigs are called kits or pups. They are born after a gestation period of about 59-72 days, and are typically born in litters of 2-4. Kits are born fully furred and with their eyes open, and are able to walk and run within a few hours of birth. They are dependent on their mother for milk for the first few weeks of life, but begin to eat solid food at around 2 weeks old. Kits are considered to be adults at around 6 months of age.
