you could also freeze it and try f/t with the snake! I am unsure of the age or weight of the snake but it sounds to be very small so you might have a hard time getting it to eat f/t unless you have gotten it to before or the previous owner had. And if it is too young and was taken from the mother and not weaned yet it will prolly die because it was still on the mothers milk. But in any case you can try dog food or something of the sort rats will pretty much eat anything.
