My ball python has refused food for the last three weeks. I know this is normal for them to sometimes stop eating, so I am not really worried about that. My question is at what point of weight loss should I get worried?

In the last three weeks, he has lost 6 grams, so he is now sitting at 174. Is there like, a limit on weight loss, that if he goes down far enough, I should take him to a vet?

Thanks guys ^.^
