Oh ok, well, until then, it's very important you feed him the pellet mash regularly (4-6 times a day), keep him indoors and as comfortable as possible. Keep harrassing your dad to try take him tomorrow and hopefully he will agree if he understands how serious the situation is. Considering your age, your doing a great by your piggie, Keep at the syringe feeding. Hopefully other members will be able to help you even further, but it's quite late, so you might have to wait until morning.
If your worried throughout the night, you can always post here, hopefully someone will reply quickly enough.
lots and lots of luck with your little one, keep us updated! I'm sorry your both having such a difficult time.
