I have a pregnant boa. She has been kept with a male due to room restraints. I had no intention to breed her. I wanted her to get a bit bigger. She's 7ft now. I didn't cool them down, but she is quite rotund. She ate 3 large rats 3 weeks ago. She did not lose her appetite.

Seeing as I have no idea when they went at it, I don't know for sure when she had her P.O.S. I believe her last shed was about two months ago. I have never bred any boas before. What signs should I look for on when she's ready? How big should she get? She's huge.

Thank you for any help.
