Did his last meal bleed at all ?? One time roxy was being fed a few days before she shed and the rat bled a little.........i guess i didnt get it all off of her becuase on her shed there were three little red dots (obviously blood)

Im kinda confused tho.....did you find the blood on the snake or on the shed ?? if you found it on the snake well then.......disregaurd everything i just said,lol
