this is a bit complicated to speak about but lets try. The poo did it look like a cats normal poo? With some liquid and stuff at the end or was it a whole mass of loose goo? Often they will pee and poo one followed by the other and you get liquid with solid urnates (a really well hydrated snake will have lots of liquid and some white urnate dehydrated you get more white less liquid) Liquid and poo isn't cause for concern but runny poo is different.
