Evolutionary relationships of FcaPV6 to other mammalian papillomaviruses, including those previously identified in cats (Felis catus). Those papillomaviruses previously identified in cats are marked with animal symbols and in red, along with their respective genera. FcaPV6 is proposed to fall as part of a proposed new genus. All virus names contain their associated GenBank accession numbers. The tree is rooted using six nonmammalian papillomaviruses that have been removed to improve clarity. All horizontal branch lengths are scaled according to the number of amino acid substitutions per site, and the * denotes nodes with SH-like branch support values >0.95.
