I went to the local shelter today looking for a buddy for my piggy. They only they had one, a 7 year old, totally brown guinea pig with short hair. Female, mind you, so not a male like we're looking for. The thing is, she was huuuge, twice or even 3 times the size of any guinea pig I've ever seen. I thought females were supposed to be smaller than males. Was she just incredibly overweight? For a minute there, I thought she was a marmot, she was that big. She seemed happy though. I'm wondering if she is fixed whether she'd turn out to be a good buddy for mine (a 1 year old male of average size). I'd be afraid she'd squash him. I feel kind of bad for her because probably no one will want her because she's so old too.
