I have a male hamster and a female hamster living in separate cages. Is it possible for the female to get pregnant?

They can touch through small gaps and both of them can go where the other has been.

If they are placed together, maybe.

If they can touch through the gaps, it may be possible; I can't be sure of course.

They have to have sex to get pregnant. We usually use the euphemism 'mating'.

Dear me - next time make sure you go to your biology classes. No.

Not unless they have learned to open the cages themselves.
