Is my snake pregnant?

[ConcinusMan]

Even if it were gravid, i'd be surprised to see a healthy, or even alive, baby...

Not a chance IMO. The snake is too weak and emaciated to even push anything out properly I think. Heck, whatever is in there might be rotting.

Sorry, I replied wrong...

She's not acting normal...

But she will eat..

When you say she isn't acting 'normal' what do you mean? Is she just acting listless and lethargic, or does she appear to be in distress? If the animal is really suffering, the right thing to do is to euthanize it, but if it doesn't appear to be in pain, then IMO there's nothing wrong with continuing to offer food and trying to keep her as comfortable as you can. Maybe you'll get lucky and she'll go peacefully.
If she's in pain though, euthanasia might be the only way. It's a tough decision to have to make.

Keeping you and your snake in my thoughts.
