[PIGGYMAMMA495]

OK. Number one let me first start off with saying my advice does not replace the advice of a trained vet who is trained in exotics.
They need immedaite vet attention or they will die.
You shouldnt be bottle feeding them. Guinea pigs should be syringe fed critical care by oxbow which you can get from a vet.
I hope you arent feeding them cat or dog formula. Milk based products are not good for pigs in general. They do not need it because within a day they are eating fresh hay and pellets. They also can be fed by syringe and supplemented if the mother has no milk. She may just need a shot of oxytosin from a liscensed vet to get her milk to drop.
Where did you get the pig who was pregnant? Im hoping you did not intentionally breed her.
As for the babies what are their weights? Did the mother properly clean them and bite the umbilical cord? Is the mom being a good mom or did she abandon the pups?
Keep track of their weights a few times a day. You do need to get them to a vet immediately. You need to syringe feed them a pellet mash. Get water and make the pellets into baby food consistancy. Syringe it and give them what is recommended on the GUINEALYNX.COM for the hand feeding section.
I would also add that you need to syringe feed them hourly, at first, it will have all guidelines on it.
AFTER you visit a vet pleeeeeease post and update all of us on thier status. Pictures will help as well.
Make sure they vet is a exotics vet.
Are they boys or girls? What are their names?
Also you live in CA. There are ton of people from CA that can help you find a good exotics vet.
