Ball Python dehydrated??

I just got my ball python a little over a week ago on Tuesday. I fed him a pinky on Saturday and he ate but the past couple of days his skin on the sides of his body looks pinched! Is he dehydrated because he has a water bowl and the humidity is between 60% and 70% in his cage. Please help I am very worried!!

Pics will be really helpful here. Also, how are you measuring your humidity? If you have one of those round analog gauges, I guarantee it's not actually 60-70%.

Also, welcome! We always love seeing new faces around here!

He probably needs something more substantial to eat than pinkies. At the very least, he should be eating adult mice.

You can try soaking him a bit just in case, but it probably has more to do with eating too small of a meal.
