So I've posted before about my Het albino who wouldn't eat for me, so today I put another mouse in his cage. He had me scared at first cause he was moving away, but he finally ate. How many live feedings should I offer before trying F/T?

Karnage Royals
1.0 Yellow Belly (Leather Head)
0.1 Bumble Bee (Karai)
1.0 Het Albino (Raphel)
0.1 Het Pied (Diamond)
