Might have tried pooing or peeing on ya. Lol. Yes sounds funny, but it happens. Jut a week back before feeding my snake, my snake poo’d and peed on me.. And I saw it in the act!!! I pic my snake up the cloaca didn’t seem big or about to poop. Then I showed the little kids the snake and etc etc, and a hour or so later I picked up the snake and the cloaca looked larger and it got bigger and his inside could be seen then he relieved himself on our coach!!! It just squirted out of his old bum.. lol a 4 ½ foot Bp can really relieve a lot of himself, lol. So maybe your snaked tried to go but he couldnt...?
Still too small? Plz lemme know. Sorry about this. I didnt knopw it was so small! lol
