My snake peach is aggresive as heck when it comes to the kill [f/t]. But afterwards she takes her sweet time to eat it. Sometimes she just goes back in her hide till we shut the tub, then she'll eat in privacy about 5-10 minutes later. Another of mine doesnt even wait to "kill", he just starts swallowing right off the tongs. I just think he's a lazy snake lol.
I guess it just depends on the snake how long it takes for them to eat.
