Hello so my 3 years old python is only eating once a month. I tried a couple of time but he would refuse a couple of time then eat then the cycle would repeat. I heat his rats in a bag floating in hot water after leaving it in the fridge overnight to defrost. my younger ball python eats every two weeks and has never refused a meal so it worries me that he isnt eating as often.He eats medium rats and seems to be able to swallow and disgest them fine.

Should I be worried or is this normal ?
