Mine are usually good 2-3 days later, but I also don't handle my snakes like most people so theirs. Just for cleaning and maintence and such.

And, I don't know if it's just me, but a rat pink seems a little small for a 73 gram snake. I would use fuzzies, atleast. And when feeding more than one, let him finish eating the first one and give him a few minutes to adjust his jaw and get the first one down, then throw the other one in there.
