I’ve been intrigued with these guinea pig breeds for some time, so I did some research to correctly identify the breed of these piggies, so the ginger-brown & beige piggies would classify as Californian Guinea Pigs, where the white ones with red eyes would be the Himalayan breed, because the Californian white do not come with red eyes
Also I discovered that with the Himalayan the intensity of the darker fur on the nose changes depending on the temperature!
