Guinea pigs, in a swimming pool. Why the heck not? I mean, other than the fact that they're probably pooping in the swimming pool, which is pretty gross. But hey, as long as you're willing to clean out the water, then this amazingly adorable, somehow absolutely appropriate for a Friday afternoon photo of guinea pigs bathing on Boing Boing will do. Yes, it'll do, pig.

No, I’ve had pet guinea pigs and rabbits that enjoyed swimming in shallow water (kiddie pool), and never saw the telltale signs of one relieve itself in the water. Rabbit claws aren’t so great for plastic kiddie pools, however…
