I had a similar situation this year. My OG went 10 MONTHS without eating (from the time he was 7months. We had tried moving it up in weight for rats, getting him from smalls to larger smalls/ small mediums.. and that very day he stopped eating. I continued to try to feed him every week, moving back down to smalls, than weaned, and eventually pups and he never showed any interest. I TRIED ALL THE TRICKS. I tried different sized ASF.. Nothing worked. He never lost any weight but he got VERY thin.. I started to freak out.

About a month ago he started striking at the prey, but wouldn't constrict. He was always the sweetest most "sociable snake," I owned and he started acting aggressively. I took him to the vet last week ($120 for an examination), to make sure there wasn't anything I was missing during my own examinations, that could be causing the fast. He checked out fine. She told me to try gerbils.. Determined to avoid gerbils at all cost.. I tried a pup this feeding again..

He was doing his striking, almost like a cobra, but wouldn't constrict. The rat got freaked out and ran beside him, he turned to striked and kinda rolled into the constriction. It was almost like he forgot how to constrict after all this time. HAHA. But he killed it, and he ate it ( I am very proud of him)

I guess my point is not to sweat it..

I would take it to the vet if your really worried, but BP's are very resilient and can go a long time without eating.
