I accidentally thawed two rats. I don't want the other to go to waste. The snake is about 42" +/-. His previous owner had him on mediums, but after a feeding incident I was advised here to switch to smalls, so I've been giving him one every 5 days. He has been on the thin side since we got him, not unhealthy, but he could use some more flesh on his bones.

Thanks for any advice. I don't know what answers I'll get at 1am my time. I'll err on the side of caution and toss the rat if I must. I don't want to give him a meal too large to handle.
