Seven months off feed

I will add my .02 in here....I think the temps could be a little bit warmer but I dont think that is the major problem here...The cool side is definitely too low but I would be more concerned with a RI with that...Second...It is not alll that uncommon for balls to go off feed when they hit that infamous 700-1000 gram mark...So you have two factors that could be working here..breeding season and again the 700-1000g wall.

I would continue to offer every week. Maybe try a live mouse. For whatever reason BP's change their mind sometimes. If that dont work after a few tries I would go with an ASF. That usually will get a problem eater to go. I know some people might balk at that idea but the snake has lost a noticeable amount of weight now and its time to get it eating. I hope this helps you. Let us know how it turns out for you

A lot of good info in the posts above. I have never really had a situation where my bp(s) didn't eat but one of them is a finicky eater. He will only eat dead and it has to be on a paper plate which is totally confusing to me, or maybe just a coincidence. I use f/t and if I try dangling it with forceps he shows no interest, if I lay it in his enclosure, he won't touch it. If I put it on a paper plate with the head propped up a bit, he suddenly takes interest /boggle

My girl likes me to dangle it with the forceps show she can strike it.

I guess my point is you might just need to figure out the sweet spot (temps/husbandry/distractions). Your enclosure looks a tad busy and perhaps you could try introducing smaller food as well.

You definitely don't want to wait too long before seeking professional help though imho.

Good luck
