It's more of a whistle, and seems to be used for social communication as
well (individuals kept as pets seldom whistle - AFAIK - but colonies kept
as lab animals can be very noisy.

What "non-rodent" is more closely related to rats, mice, and squirrels than
guinea pigs are? (That's what polyphyletic implies.)
