@ EL and Albert ... Thanks for the heads up, hopefully I get lucky .... I looked at both perfect prey and Layne labs before making my order with Rodent pro ... I couldn't bring myself to swallow the cost that Layne labs came out to and perfect prey was also out of med rats .. luckily I played it smart and only ordered a 2 month supply from rodent pro instead of the usual 4 to 6 month supply that I like to order. I would love to stick with Big Cheese but like Eric said I am getting so frustrated with their lack of med rats that I don't know what to do. If they can get their supply and demand issue under control I would gladly go back to them but until then it's just not worth my money as 80% of my order is usually med rats.
