Hi, i recently bought a ball python from petsmart, it seemed healthy when i bought it this last friday. I actually fed it a live white mouse the same day and it ate it with ease. it is now tuseday the following week, and i noticed the ball python now has a hissising sound when it breaths. it sounds like a popping sound. it also opens its mouth partially. it seems healthy. it stays in its hide most of the time it is more active at night when i put in the infared bulb. btw day time 92-96 degrees hot spot 84 ambient. night 87.3 hot spot 82 ambient. I dont know if i should wait and see if it goes away and tough it out. Or return it tomorrow for a new python. i really like this ones personality, its very docile and dose not curl up when i handle it? i liked how it also ate right off the bat. no problems with feeding and very personable. I am torn dont know what to do. there is a 14 day cut off and want to return it before its to late. any help or opinion would greatly help. basically is it worth it to keep it?
