I am going to be moving from Texas to Michigan very soon. I have had Jade, my BP, in a 20g critter cage insulated with cork for the last year; however, when I bring her to Michigan I will be getting her in a whole new set up and was leaning towards tubs for the added insulation I'm gonna need during the winter. The apartment complex is cool with Jade as long as she can't get out so I was wondering if there are any really secure tubs where I wouldn't have to worry about her lifting three piled up books to get out? She is about 900 grams and probably around the 3 ft mark.

Thanks!
