Thats why I said just what it seems like to me. According to rodent pro the nutritional values seem to be the same. Just stating iv had a boa and ball that hit "growth spurts" soon as i switched to rats. and many other people have said they noticed "rapid" growth when switching to rats from mice. No study here just saying in 2 months my boa grew 2x the amount he did in 6-8 months on mice![]()
