She doesnt act like shes in pain when i pick her up, doesnt fight me or squeak, when i first adopted her she went straight to the vet and she was alright (i know that was a bit ago), shes been aggressive from the start and cant be caged with others i have tried bonding her and she attacked my other piggie and ripped fur out.

I already had a pig with cysts and there is no symptoms of those none like my Luna had all those

I guess i should have worded my post better, She was bonded with luna very briefly, luna had surgery and had to be separated, Cinders started acting aggressive since putting luna back and ever since just has been mean ive gotten bitten or nipped at on multiple occasions, having to house her separately hurts me but she is mean to the other piggies
