So I know it's pretty easy to see if you're underfeeding a snake because they get that triangle look to their body and you can see their spine(mine came from petsmart like that).

My question is though, how can you tell if they're overfed? I mean I'm pretty sure my snake would eat every other day if I offered it food, but obese is about as bad as under fed, so I'd like to avoid that as much as I'd like to avoid the triangle shape.

So what signs indicate an overweight BP?
