[Gpdd] Behavior ( biting piggy)

[hypnotic95 at aol.com]

Hi everyone- I wrote about a month ago about my fighting pigs.  Since  then 
we put them in different cages and everyone is doing great.  My  question for 
everyone is my  pancake (boy)  just started biting his  cage as in 3 days ago.  
He does it all the time now and it makes a horrible  sound.  He has plenty of 
things to chew on in his cage and he gets plenty  of play time outside his 
cage.  He bits the side of the cage which is  closest to the other cage where my 
other boy waffles now resides.  I just  don't know if this is normal, or if 
there is something I can do differently to  get him to stop.  I'm just worried 
about his teeth with all this  biting.  The last time he was at the vet about 
a month ago they said his  teeth were fine.  SO if anyone has any advice about 
what to do for my  pancake please help.  Thanks so much   
Kelly with pancake, and waffles.
