Yes of course they do because they are very clean animals
yes they are cleaning themselves.
Surprisingly, yes. My guinea pig loves to lick fingers! In many ways, a guinea pig is much like a dog. Do they lick themselves? No.
They lick them.
Guinea Pigs, unlike cats and dogs, don't lick themselves. Therefore, Guinea Pigs don't have hairballs. Improvement: However, some guinea pigs are prone to "barbering" to eating fur off either themselves, other pigs, or their human companions. Excessive barbering can lead to hairballs which in turn can lead to anorexia and weight loss and must be treated.
It means they love you.
Guinea pigs wobble because they are bored and are trying to entertain themselves.
well guinea pigs will mate and make themselves but its really just called nature
Yes, they have a great ego.
some guinea pigs love the water, others don't. Its all down to the preference of the individual
No guinea pigs cannot there wouldn't be enough space and guinea pigs aren't supposed to use exercise wheels that are usely in hampster cages (because they can easily hurt themselves).
It's different for every animal, but typically, babies do wean themselves. I have animals and though most wean themselves, sometimes you have to separate the baby from the mother for a period of time and then you can put the baby back in. At least it's easy to do that with guinea pigs...
No the owners take care of them
