I have also had both. I am sure you know how much the rat cage needed to be cleaned... A guinea pig needs a little more cleaning, every few days depending on the size of the cage (bigger is better). Guinea pigs also need hay to stay healthy, which can make a big mess also. I am definately a fan of both, a piggie that is given a lot of handling will really enjoy being played with, like a rat. Mine also gave kisses. They squeek and squeal when you come to the cage to see them. They hop around when they are excited and run around like crazy when they are exstatic. Piggies are a treat, and a joy to have. Piggies should live 5-8 yrs, rats 2-5. My rats all lived about 3 yrs. Just as a side note... piggies look really funny when you feed them treats:) Try small peices of oranges... very cute.
If you hav any other quesions about pigs let me know.
