Reptile Show and Came Back with..

Two tiny rat babies. I went to look for a lizard and ended up with something warm blooded haha. They are little but with perky ears and squinty eyes. About half that were in the bin had eyes closed. I've got a little carrier set up with blankets and a sock that they curl up on. I'm going out to get some milk replacer but they are nibbling lab blocks and eating some baby food so far. Any other suggestions for babies this little? :) I'll try to get a picture for size
