It really depends on a few things, whether the animal absorbed it's entire yolk, whether the hatchling was a big hatchling etc.
I generally consider assisting after 6 refusals.
What I do is if after 3 unsuccessful feedings I offer another prey type, in your case I would suggest offering mice hoppers the next time around. It might not be what you prefer but not all BP start successfully on rats.
