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.
