Which is harder to take care of, a Guinea Pig or a Kitten/Cat?

Guinea Pigs are highly sensitive creatures that need to be socialized constantly. A cage or preferably, a room needs to have more than one guinea pig. Theres more specifics that make it different from owning other pets. They cannot be around areas of noise, and can't be constantly held. Hay or bedding needs to be changed every other day, unlike cat litter. Guinea pigs also require baths, cats don't. They ARE bigger animals, that's right, but they usually can maintain themselves, they are good at being independent in many settings, inside the house and outside.
