we just got rid of guinea pigs. My wife and her friend thought they each needed one of the cursid things and of course it turned out her friend could not take and we where stuck with two! She quickly realized the pain keeping these things, they where the most stinky things in the house even more so than the mice! They would sqeak and squeel all the time and pee so much it was crazy! Once they matured some we found they where both males which is why they where such a hassle together.
