Yes, but make sure that they are kinda the same age

Another guinea pig of the same gender. Guinea pigs are social creatures that get lonley if kept on their own. Most people choose to keep female guinea pigs in groups as you can have problems with boars (male guinea pigs) fighting. You can of course keep two or more guinea pigs of the opposite gender but unless you want baby piggies it's not a good idea. Hope it helped.
no
No. Mammals cannot change gender without medical intervention.
Only to another guinea pig of the opposite sex.
It depends on the gender. A female is called a sow and a male is called a boar.
Guinea pigs are fine with towels, it doesn't hurt or annoy them in any way. Guinea pigs love soft materials so you should use them especially when cuddling them!
the opposite sex
NO they do the exact opposite they are way more scared of you
no... but if you don't want a lot of guinea pigs than i suggest getting two male guineas...
No, guinea pigs should not eat sweet and salty nut bars. These snacks are high in sugar, salt, and fats which are not suitable for the sensitive digestive system of guinea pigs. It's best to stick to a diet of hay, fresh vegetables, and pellets specifically formulated for guinea pigs.
You dont have to, unless you are keeping it with the opposite sex.
Chives are vegetables, so it should be okay.
