Apparently it didn't work that well as you just said
My Petco is absolutely frying those babies. Several are having shedding problems because the humidity is so low, about 40%. Feel like going over with my tweezers. I spoke with the manager, but who the heck knows if he did anything. I'd buy them all, but I do not know if I could resell them to good homes.
I still say the more you buy, the more they buy, the more that die. Or are at least mistreated.
