Hi, My python Mitch has always been fed live, since her first feed. Lately some of her "captures" haven't been so... well here are the pictures...

She grabs them where it looks like the rat is going to get away. And the rat scratches and flails around. Is it because i cover her tank with a blanket so she can have complete darkness during a feed? What should i do? I dont want her to get hurt!
