To keep it simple: my bp hasn't eaten in a while (he's very tempermental) and I'm wandering if the prey size is a possible reason why. He is about 2.5 inches around at his girth and the rats look the appropriate size, but if the rat is too small will he just leave it? I feel like the only problem would be if the rat was too big, but now I'm questioning the opposite end of the spectrum. Thoughts?
