I'm new to this hobby so you can take what I say with a grain of salt but recently I ordered rats for the first time and when they arrived I couldn't believe how beautiful they were. Compared to the f/t rats sold at my local reptile store they were fantastic. It only took 3 days to get them and when they arrived they were packed in ice and still very much frozen. I only have the 1 point of reference but I know clean and healthy. They were twice the size of the local rats and 1/3 the price. The shipping cost is a little pricey but it was worth it. Here's the link if you are interested.
