my girl mount on each other, are they normal?

[Rosina]

One of my girl always hop on the other girl, they are in the same cage for about a month now, is it normal?

 

[dagwellismypigy]

It's completely normal. It is a sign of dominance.

 

[rabbitsncavyluv]

It's normal, a dominance thing like dagwell said. Are you sure they are both girls though?

 

[Rosina]

yeah, I looked and they are both Y.
