We really needed an "All of the above" option LOL!
Most of us who have more than 10 balls are fully aware how picky they can be if not started on a certain food as hatchlings.
Less than half my snakes will take F/T
A few prefer live mice.
A few prefer Live rats.
One is extremely picky and will only take ASF's or mice even tho she is large enought to take large rats.
