Just to add in here I recieved my first RodentPro shipment of Weaned Rats (Icc took one last night!! it's a size up from the pups I was feeding and he took it down with no problems) I recieved my shipment a day early! and the mice were very well packed, totally frozen and came out to about .68 cents a piece for a bag of 20 - shipping was expensive though.. I think my total was like 27 bucks or so (incl. Shipping) which is pricey I know but I found a frozen feeder supplier around here so I won't have to do that again.. but if you think about it 30 (I'm rounding ) bucks for 20 weeks of food is a decent deal and plus I had lots of fun blowing stuff up with the dry ice Plus rodentpro rodents are always sized perfectly it truly is amazing when you look at the bag and all of the mice look EXACTLY the same haha.
