Guinea pigs can eat and drink normally shortly after birth, since they are born quite well developed, however they need their mother's milk until at least 3-4 weeks of age and then they can be weaned.
a bol or a bottle
they should eat the normal guinea pig food and drink from the water bottle.
take it to the vets
Your guinea pig will drink it's water
no. they lick salt. they get thirsty. they drink. be worried if it doesn't drink a bottle a day
Does your Guinea pig like peanut butter ? (They generally do) rub peanut butter on the drink bottle outlet and eventually after you have done this many times it should eventually learn that water is also coming out, let it get a bit thirsty as well
milk
when my guinea pig had babies i held her and she was fine
One would be crying and throwing his or her guinea pig
Pups or Guinea piglets.
you can't. unless you have a trained guinea pig that somehow can talk to the baby and say what you want to tell it.
The only problem would be the size. Guinea pigs drink MUCH more than a hamster would, so generally you would need a larger bottle. Also, if you used this bottle for a hamster previously, you would need to make sure it was cleaned well before using it with another animal.
