No it is not true that only mice make monoclonal antibodies.  These are
produced by fusing spleen or lymph node cells with a myeloma cell line.  The
monoclonal is obtained through a process of cloning these fused cells to
select the one cell that is making the antibody.  Monoclonals can be
generated from other species such as rat, hamster, rabbit and human.  There
are even references for bovine monoclonals.

Polyclonal antibodies are obtained from the serum of animals that are
immunized.  The serum of an immune mouse is also polyclonal.
