fed exes hod facilities are in metal buildings with fans not AC, would be best to take an early lunch break or have them delivered to your work. the livestock themselves should be fine, however the temperature is the issue. you might have a nice gumbo if your not careful, and FedEX does not guarantee any package that contains live cargo. it is actually against their policy to ship it. odd, since they solicit their business to pet stores, huh?
