I don't know what Petco these photos are from, but this Petco is pretty lackluster. Grooming looks like a little hole on the wall and training isn't really present.
As normal, it smells. I think it's the ferrets and the fact that they house too many pets per cage. I've even seen a dead white mouse under a pile of live white mice...like it had been suffocated by the mass. The employees seem like they are bored and just there for the paycheck. Saltwater aquariums are a nightmare, and bugs everywhere around the reptile section.
Not worth the effort really.
