Rehoming Ball Python Snake

I am rehoming my ball python. Ive had her for about 6 years and she no longer gets the care she needs anymore. She hasn’t been eating and is a bit skinny, but I cannot afford the vet or frankly her anymore, and I have a cat that is constantly trying to get to her. I really want her to go to an experianced owner and am willing to give her and her whole set up for no charge as long as it’s someone who had kept snakes before and knows what to do for her. I don’t have the time or resources for her anymore and my house heats up really quickly in the summer, which causes problems with her heat lamp and such. While I am willing to give her tank with her I think that she would do better with a size up.
I have tried to rehome her to a rescue, but haven’t been able to find one willing to take her. I just want her in a good home since i have had her since I was quite young and she really means a lot to me. She is a normal morph. Please email me any questions you may have. She has always been a good eater which leads me to believe something is wrong with her environment. She is in a 30x12x12 Exoterra tank currently
