Hi, I just got a 3-4 year old girl from my friend who didn't want her anymore. She was on poor food (with seeds) and also she had a ball for her. Shes pretty fat, compared to my other piggies shes almost twice there size... Shes pretty mellow and when I pick her up she squeaks. I thought that this was because she didn't know me very well and i only got her on saturday! Everyone is getting along good (that goodness, I think all my pigs are pretty social and like being around each other.) Anyways, I will take her to the vet, but I'd like to know how much a reputable vet visit would cost (an estimate). I also want to know if I should separate her from the rest, they've just gotten aquainted so I'd rather not, but I dont know if this is anything like she could pass on. She is eating and drinking fine also.. Thank you! also the lump seems bigger than a dime but smaller than a quater- I didnt want to feel around to much in case it is sensitive!
