Petco or PetSmart for guinea pigs?

NEITHER! I would try craigslist or pet finder. their may be a shelter close by that u didn't know about. Yes many pet smarts and petcos deprive the animals of enough water and the proper nutrition. They also house males and females together so u r at risk of bringing home a pregnant sow. Female guinea pigs are ually mature at two months males are ually mature at 3 months. hope i helped.
