i had two dekay's snakes and one was so small it looked smaller than an earth worm!! but after some time it died from eating issues. it couldnt ever eat a small piece of worm. it would take 30 minutes for him to finish one small piece. but every other time he would spit it out and leave it be. so i think it was form starvation. it was very sad. i felt bad but they dont get very big at all about 15 inches. right?
