Hi Bev- I've been away from my computer for a few days. I'm sorry I didn't get your response sooner. You can use infant soy formula for humans. Just dilute it the same way as for a baby with warm water. If you place a drop or two in their mouths, they will usually take to it really quickly. Then you just hang a water bottle with the formula in it, on the cage. It isn't bad for momma to drink and they usually help themselves too. MAke sure you provide a lot of loose hay. Usually after about a week they will learn to drink water from the bottle. They don't need a lot of help from mom in most cases. If they look healthy and are running around they're probably fine. If you pick up a baby and it starts chewing and biting at your hand, then that pup is in trouble and needs some help fast. They do that when they are desperate. But like I said, it has been over a week and if your pups seem active and perky, they are most likely fine. I have heard of people taking pups away from mom VERY early (I don't in anyway recommend this). They wean the pups within a week and they go through a period of reduced growth rate, but catch up quickly after they get going on pellets. If yours are eating pellets and veggies you should be already out of the woods. Don't worry...take a deep breath! They will let you know if they are not ok, if you observe their behavior. BTW, aren't guinea pig pups the cutest??? ;)
