Pigs have panoramic vision of approximately 310° and binocular vision of 35° to 50°. It is thought they have no eye accommodation. [82] Other animals that have no accommodation, e.g. sheep, lift their heads to see distant objects. [83] The extent to which pigs have colour vision is still a source of some debate; however, the presence of cone cells in the retina with two distinct wavelength sensitivities (blue and green) suggests that at least some colour vision is present.

So, if your furry friends has water and hay, and their environment is clean, they can live without you. Even forever. Ouch, right?

So, realistically, you can always be away for a few days at a time, and if possible, nothing more than three days, which frankly, is pushing it. Every once in a while, you may need to be away from your furry piggy for a few days or a few hours. Like other living beings, you must ensure your guinea pig has enough food and water.

The pig is most often considered to be a subspecies of the wild boar, which was given the name Sus scrofa by Carl Linnaeus in 1758; following from this, the formal name of the pig is Sus scrofa domesticus. [15] [16] However, in 1777, Johann Christian Polycarp Erxleben classified the pig as a separate species from the wild boar. He gave it the name Sus domesticus, which is still used by some taxonomists. [17] [18] The American Society of Mammalogists considers it a separate species.

However, they don’t need you to survive as long as they have their basic needs met.
