Bp...not eating

My ball python had a very good feeding response every time i fed her,until now....she refuzes to eat,she looks at the mouse interested bun then she goes away...the only
thing that has changed are the hides...they are now bigger becausse she barley fit in the old ones,so now she has little space in her terrarium because of the new bigger hides...could that be the problem?

Yeah, she might be missing her old hides. Often BPs like the hides they barely fit in the best.

leave the new hides as they are and let her adjust. This is time still where older ball pythons refuse feedings.

How much bigger are the new hides? If it doesn't "hug" her (or come remotely close to "hugging" her), she may be feeling insecure...

If you want to give her new hides, change them over one at a time. See if she likes the new one. If she starts using the new one, switch the other one out.

I had 2 hides, one too big and one he was barely fitting in for Paradox. He definitely did not like the too-big hide, hardly used it. I got 2 new hides that were inbetween the two. He took right to them no problem. But I did switch them out one at a time.
