Ball python kept away from people too long?

He needs to gain both weight & strength...like any creature that's underfed, he has lost both muscle mass & tone. It will be a slow process for him to get
healthy...you might have his stool checked also, to make sure there are no internal parasites* sharing his food or other issues where simple treatment could
be of help to him. (*He was fed live previously-)

It sounds like he is in good hands now.

I just adopted a 3 year old male albino that is smaller than your snake. From what I understand, he was rarely if ever handled or fed and they had a small unregulated heating pad attached to the SIDE of his tank. When I got him 4 months ago he was 250 grams and he is about 330 grams now.

I started out feeding him 1 large mouse every 10 days then slowly increased to every 7 days. He constantly acted hungry and now eats 2 large mice every 10 days and is ready to be bumped up a size in prey. This guy won't refuse a meal even during shedding. I handle him about 30 min every 3-4 days and he is skiddish at first but settles down after a few minutes.

It's very rewarding to take in snakes that need some "T L C"...it really feels good to turn them around into healthy & relaxed pets.
The changes are very slow at first, but then the progress speeds up until pretty soon they are SO much better than when you got them. :gj:
