Hello there Ellie,

It depends if you are going to try feeding live or frozen.

Also, regarding the neglect, if your friend decided not to offer him food weekly over the past 6 months it would definately be that. If he's refusing food for 6 months it may also be, in that basic husbandry efforts had to be ignored to the extent that the snake was so stressed out he would not want to eat for that long. It could be that your friend did not educate herself enough to know what he required to meet his needs, and less a case of intentional neglect, however either way the responsibility most likely falls to your friend's care.
