as some of you may know, i own one ball named zeus. he is acting a little odd.. when i picked him up, he occasionally gave a wheese sound. not constantly, once every ten seconds. and is acting very twitchy. he is not in shed and has no skin over his mouth and or nose. can you guys help me? i dont want him to be sick... BTW... he has grom 50 grams hevyer this week alone without feed. getting to be a big boy!! p.s. it is 12:30 here in colorado, and i am tired. so sorry for spelling mistakes...
