the exact same thing happened to me today too! she drew a lot of blood, but this isnt the first time she's struck.
it has been a lot hotter these past couple days and im wondering if heat has any affect on aggression. i wasnt moving too fast around her, but maybe she was just agitated.
im also curious how often you all handle your bps. i remember reading somewhere that they dont like to be bugged too much...
Feed on fridays. Sat and sunday is rest days. So between mon and thur. So maybe once or twice in them 4 days for maybe 10-20 mins tops
