Eupleridae
Fossas form monogamous pairs, while species in the genera Galidia, Mungotictis, and Salanoia live alone or in pairs, suggesting that they are monogamous for one breeding season only. Mungotictis individuals live in small groups with several adults of each sex, but it is not known if all of the adults in a group breed. Cryptoprocta only live alone, suggesting a polygynous or polygynandrous mating system.
