Just went to get some rats and I always like to look through the windows on the freedom breeder rack and in the very bottom tub they had a female for sale. So of course I bought her, she weights a tad over 2300 grams and has a pretty cool color up towards her head. She also might be gravid from a male with similar colors.
Here are a couple pics of the color im talking about, I dont know if anything is going on here but if not shes still a big girl.
