Since about last Sunday by baby ball python (I'm thinking he's about 9 months- 20 inches long but I'm unsure of his weight) has been acting cranky and very inactive. On Friday I fed him one hopper mouse (the pet store was out of adult mice) which he took in under five minutes but not the second one. Usually every night he's up around the cage stretching up the walls, and is generally pretty active. I got him in late December and have only seen him shed once (Feb. 1 or maybe a few days before was the date of the last shed) and he is also being jumpy when i'm moving around outside his cage or when I open it to change the water, which is how he acted before his eyes got cloudy the last time he shed. Also he's chillin mainly outside of his hides in the back of his cage, but keeps yawning and pushing his head against the glass and other objects in his cage when he's moving around. I've noticed what looks like more saliva in his mouth over the past week, but no bubbling or mucus or wheezing. I'm just wondering if he's probably about to shed because he's been acting this way, I'm thinking that he's uncomfortable in the old skin and is ready to get it off that's why he's rubbing his nose against stuff. His eyes are still clear which is why I'm unsure if he's about to shed. His temps are 85-90 on the warm side and about 80 on the cool side and humidity I keep between 40-60% but this past week I have had it in the 60's. Any input would help me out a bunch thank you!
