I go to this Petco every 2 weeks and have been for a couple of years. I have Hermit Crabs and am well versed in the care of them. I stop there to see what they have and the humidity level and heat is too low. I brought it to the Mgrs. attention. 2 weeks later heat is up and humidity level is still way down. In a nutshell I have been fighting this battle for over 2 years. The corperate office agrees the humidity needs to be higher and told the manager what to do. He has yet to do it to this day. Now I just don't go in.
