I am pretty broke and I have heard that snakes can go a whole month without eating. I want to know if it is bad to feed every other week on an ongoing basis.
Being a responsible animal owner means provide to their needs however if having an animals becomes a burden, you need to re-think animal ownership. Did you know when you purchased your BP that you were making a 30+ year commitment?
Now I also understand that sometimes things happen and money can be tight however in this case the responsible thing to do is to re-home the animal temporarily or permanently.
I can't feed him adult rats yet because he regergitated the last medium one I gave him. it stretched his neck way big.
You might want to brush up on some basics about BP such as how to appropriately feed them.

You should feed a prey slightly smaller then the girth size once a week and nothing larger then a small rat (4 weeks old 45-65 grams) to an adult BP.

Because your BP can take a large prey does not mean he needs to.
