At my petsmart they're all healthy and active and the lady who worked with the small animals said she played with them everyday

I got my two piggies at a petsmart and they're both healthy.
Of course that's just my petsmart, but yes, I've seen pet stores with HORRIBLE conditions!
I went to petco to get some extra hay because I was running low and didn't have time to order some offline, and the guinea pigs where in small tanks with like 5 in there, and there was a female that was alone--and pregnant.
All the other animals where kept in bad conditions as well
