That is horrible, The manager must know about this and probably doesn't care, (it's awful) and the commercials are obviously fake too, (duh!) I've had a bad Petco expierence but nothing like that! I just went to the restroom and There was dog poop all over the stall, You might be able to complain online to petco"s presidents and see if they could do anything! The animals would be better off in a shelter!
That's pretty bad! If you find out anymore or Did something that fixed the problem let us know!
