Guinea pigs make wonderful pets, but their breeding habits can surprise new owners. Knowing if your female guinea pig is pregnant is important for her health and care. There are several signs to look out for that may indicate pregnancy.
A pregnant guinea pig will typically gain weight, with her sides becoming rounder and her belly growing larger over time. This weight gain is often noticeable, as pregnant guinea pigs can double their normal weight by the end of the pregnancy. Other physical changes may include enlarged nipples and a wider pelvic area.
Behavior changes can also hint at pregnancy. A pregnant guinea pig might become more tired or less active than usual. She may eat more food and drink more water. Some guinea pigs get moody or less friendly when pregnant. Keeping an eye on these signs can help owners prepare for the arrival of new guinea pig babies.
