Typically my bp, Jackson, strikes hard and fast, then constricts for a minute or two before moving to swallow (we feed f/t), but a couple of weeks ago he just... didn't bother with the whole "kill the dead thing" routine. I must have spent 5 minutes doing the dead-rat-dance trying to get him to strike before I let off and just let him smell it, which he seemed quite keen on doing. Much to my surprise, he just lazily opened his maw and started swallowing.
