Yes, it's by weight. And it's extra if you want inly your animal cremated by itself, and if you stay while they do that. And they only have certain days they do the private cremation, etc. That said, they are very nuce and caring people.
I imagine they would, but not sure. I would call them.
The cremation cost is weight based so I'm sure they will cremated a guinea pig. I think 2lbs and under is about $90-$100
