Yep, I have 5 males breeding this year, and 3 not breeding, and not a single one of them has touched food in over a month, lol.
I usually offer smaller than normal prey during the breeding season. The males like smaller prey if they decide to eat anything, because they can digest it more quickly, it doesn't take a lot of metabolic effort to digest, and it doesn't weigh them down. They're ready to cruise and find more girls.
