Wondering what you guys think.
I think they most definitely do! I always feed on Sunday nights. Last week they all got fairly large meals, so I skipped this Sunday. When I came home from a few errands at around 6 o'clock, they were all peeking out of their hides and looked up expectantly when I entered the room. I then went to the QT room to check the temps in the new boa's tub, and as I opened the lid she flung herself out of the cage trying to grab my hand! She's a fairly aggressive feeder, but has never shown any signs of cage aggression before.
What are your experiences? Do your snakes know what to expect on a certain day of the week or month?
