Anyone feed their collection a combo of mice and rats?

I feed my snakes both but not by choice. I only have 1 source for live and they dont always have rats available. My snakes dont seem to care either way. The feeding responses are the same.

I breed norwegians and african soft furs. The ball pythons are mostly fed norwegians. I'll sometimes give a female a few ASFs right after laying to get her back into feeding mode. Males sometimes get a few ASFs after breeding season to speed up their re-bulking as well.
