JM, I found an old thread on a UK forum with people suggesting:
-They pushing because they want to breed.
-Giving them a smaller hide so they fit snuggly
-And lastly a guy had to turn his viv on it's back so the glass was the roof and had to re-arrange the heat and lighting. And it made his retic stop pushing.
I don't know brother, is up to you to try this ones. Good luck!
