We know guinea pigs are seriously cute and fluffy, but they're actually really low-maintenance, too. Famously easy to care for, these larger rodents simply require a nice mix of pellets, hay, and fresh produce, and fresh water out of a sipper tube. If you don't have tons of space or live in a smaller apartment, your guinea pig will be fine with a sizeable cage and keep to themselves. But that doesn't mean they don't love playtime, too: They make for great cuddle buddies as soon as you get back home, and you can even teach them tricks.
