Often you keep seeing posts about Western Hognose' going off feed or never eating to begin with. I went through this phase with all three of my hogs. My solution that got even my most stubborn tiny hog to eat was housing them in tiny, secure, uninteresting looking sandwich containers. I guess the security of being in a small space with a hide and lots of burrowing substrate made them feel comfortable enough to eat. I also had success with the paper bag method. No scenting was needed.
These aren't feeding pics but here is my freshly shed normal male just chilling this morning
So, if your Western hog is not eating review your set up.
