I'm very new to this... But I'm trying to do my part... I go on Craigslist alot just kinda Window shopping and since discovering c&c cages I browse looking for maybe sum spare cloroplast or grids that I can find cheap... Extra parts r always a plus... Either way I've seen this add a few times... Seems like a breeder to me... I recently gotten 2 rescues boys they are the sweetest ever... Both were so thin and scary.... Broke my heart.... They r coming along very nicely im happy to say... With alot of love n proper diet of course.... That said I will do my part to help other piggies out there....im sure this is a breeder... If u agree plz flag. Thank u so much Craigslist: guinea pigs - $1 (broken link removed)
