I got my ball about a year ago ... and it just notice when the mouth seems bleeding a little but now it is fine. I checked on my friend and she said that my ball got IBD.
and yes ... I just got Boa near the ball cages. Could that be the problem ? so far my ball haven't take any food for about 3 weeks. I did test whether my ball has stargazing by taking her tail but it didn't show up like those who got stargazing ( i check on youtube)
