[Snake lover 3-25]

Yay Sooty ate his first pinky!!!! 6 to be exact!!!! he also had some tilapia!!!! he ate it all like he had nerer eaten before!!!! he struck at them unlike any garter i have ever seen!!!! He ate alot!!! Do snakes know when to stop eating???? or will they just eat and eat until who knows what happens??? also how can i ease his fear of sudden vibrations and movements???? Do any of your snakes act very calm one second and then be off the wall crazy the next???? is that a bad sign???
