1. Contentment and Relaxation: Rolling on their backs is a sign of deep contentment. Just like a cat stretching out on a sunbeam, a guinea pig rolling is a way of relaxing and enjoying the moment. They might do this after a good meal, a cuddle session, or simply when they feel happy.
2. Playful Behavior: Guinea pigs can also roll around as part of their playful behavior. This usually involves running around, jumping, and maybe even a bit of wrestling with their cage mates. It's a way for them to burn off energy and have fun.
It's important to note: If your guinea pig is rolling excessively, it could be a sign of illness. Look for other symptoms like lethargy, loss of appetite, or diarrhea. If you are concerned, it's best to consult with a veterinarian.
