Should I be concerned? Otherwise she seems fine, she's active and eats happily. She just makes grunting barking sounds. She doesn't do it often.
Also when I put in their first hammock, the first to find it explored it then started barking and the others came running.
Their old home also had a pet dog so maybe they learned to mimic him but I don't know. Im a little worried. Help

Rats don't normally make audible sounds. When they do its usually a respiratory problem.

You should take her to the doc.
