Notice that humans are closer to rodents than ferrets are:

Take a look at this National Institutes of Health page:

Ferret:
Lineage( full )
cellular organisms; Eukaryota; Fungi/Metazoa group; Metazoa; Eumetazoa;
Bilateria; Coelomata; Deuterostomia; Chordata; Craniata; Vertebrata;
Gnathostomata; Teleostomi; Euteleostomi; Sarcopterygii; Tetrapoda;
Amniota; Mammalia; Theria; Eutheria; Laurasiatheria; Carnivora;
Caniformia; Mustelidae; Mustelinae; Mustela; Mustela putorius

while here is the lineage for mice:
Lineage( full )
cellular organisms; Eukaryota; Fungi/Metazoa group; Metazoa; Eumetazoa;
Bilateria; Coelomata; Deuterostomia; Chordata; Craniata; Vertebrata;
Gnathostomata; Teleostomi; Euteleostomi; Sarcopterygii; Tetrapoda;
Amniota; Mammalia; Theria; Eutheria; Euarchontoglires; Glires;

and humans:
Lineage (full): root;
cellular organisms; Eukaryota; Fungi/Metazoa group; Metazoa; Eumetazoa;

To see mouse info for yourself just search for Mus sp. and to see
humans search for Homo sapiens.
