Plain not with perfume or ink,led or any thing that you use to wright with or the gerbil will get food poisoning.
Yes.
Yes. Give him some sheets of unscented, non lotioned tissue and he will shred it up for bedding. Not all gerbils are the same, though, so make sure he doesn't eat it. My gerbils shred toilet paper for bedding.
Gerbils love to chew, so anything they can chew that is SAFE. Wood toys from the petstore, toilet paper roles, paper towel rolls, etc....
For fun they like to chew paper and cardboard. They also like to run in plastic balls, once they learn how!
They can gnaw on them, but they can't live on them.
Gerbils are an animal and can not be "invented".
Other gerbils.
Male gerbils can be neutered, but it is not recomended. Female gerbils should not be spayed. In general male gerbils should not be neutered unless there is a good reason for it.
Paper and cardboard that you have at home is good as well as fruit tree branches like apple tree branches. You can also but chew toilets from shops. These are usually made of wood or rope and there are best to keep gerbils teeth short.
Yes, mice are smaller than gerbils, but I think gerbils are the right size.
no gerbils are not originally from the UK but instead from the deserts of Asia. But you can still buy gerbils in the UK
Yes, e.g Mongolian Gerbils.
