I feed in a suitable tub inside the vivs. Humphrey is an enthusiastic constrictor who rolls around strangling the thawed mouse, and would manage to coat it in aspen otherwise. A paper plate isn't going to cut it with the amount of moving & constricting Humphrey does! Attitude is a hatchling & I want to monitor intake. Icabod is well behaved & probably doesn't need these precautions but...
So far no one has taken to striking at my hand as a result. Attitude tries to bite every time I open the viv, feeding time is no different. LOL.
I don't move them out any more after a cat decided to investigate the feeding tubs. No harm done, I was right there, but I think that cat (Phantom) might like to sample f/t mouse! Now the feeding tub goes into the viv, snake into the tub, then mouse, then lid goes back on viv to leave snake to eat in peace.
YMMV. This is just what I came up with after reading here.
