Jaguarundi - Puma yagouaroundi
The jaguarundi (Puma yagouaroundi) is a small-sized wild cat native to Central and South America. Jaguarundis are primarily diurnal, being active during the day rather than evenings or night time. They are comfortable in trees, but prefer to hunt on the ground. They will eat almost any small animal that they can catch, typically catching a mixture of rodents, small reptiles, and ground-feeding birds. They have also been observed to kill larger prey, such as rabbits, and opossums; relatively unusual prey include fish and even marmosets. Like many other cats they also include a small amount of vegetation and arthropods in their diet. In terms of physical appearance, the jaguarundi is perhaps the least cat-like of all the cats. It has a total length of 53 to 77 cm (21 to 30 in), not including the 31 to 60 cm (12 to 24 in) tail, and weighs 3.5 to 9.1 kg (7.7 to 20 lb).

Fossa - Cryptoprocta ferox
The fossa is a cat-like, carnivorous mammal that is endemic to Madagascar. It is a member of the Eupleridae, a family of carnivorans closely related to the mongoose family (Herpestidae). Its classification has been controversial because its physical traits resemble those of cats, yet other traits suggest a close relationship with viverrids (most civets and their relatives). Its classification, along with that of the other Malagasy carnivores, influenced hypotheses about how many times mammalian carnivores have colonized the island. With genetic studies demonstrating that the fossa and all other Malagasy carnivores are most closely related to each other (forming a clade, recognized as the family Eupleridae), carnivorans are now thought to have colonized the island once around 18 to 20 million years ago. The fossa is the largest mammalian carnivore on the island of Madagascar and has been compared to a small cougar. Adults have a head-body length of 70–80 cm (28–31 in) and weigh between 5.5–8.6 kg (12–19 lb), with the males larger than the females. It has semi-retractable claws and flexible ankles that allow it to climb up and down trees head-first, and also support jumping from tree to tree.

Both very understudied animals, so I'm not so sure. I think i will back the fossa, it is a well muscled animal and would probably be stronger then the jaguarundi.

It depends. I want to see some more pics pf the Jaguarundi such as their skeleton and their skull or a better pic that shows their muscles.

I favor the felid but this is a fairly close fight. I just think the jaguarundi takes larger prey

Dosen't the Fossa grow to larger weights than 19lbs? The encyclopedia of mammals by David Macdonald has them down as 9 to 20kg.

Anyhow I can't really call this fight but of the top of my head i'll say Fossa, only seen a Jaguarundi once at Budapest Zoo, they are strange looking things.

Again? This proves nothing.

50/50 IMO

How does it prove nothing? Taking larger prey takes more physical strength, physical strength is important in interspecific conflict... On a psychological level too an animal that takes prey of similar to larger size will be less apprehensive to fight when faced with an animal of equal to larger size. Is this stemming from your bushdog maned wolf analogy? Nature is full of exceptions, foils and contradictions with no hard fast rules, but in general an animal that takes substantially larger prey needs more strength.

Not, since both animals hunt by ambush. And there are other analogies. For example, reticulated pythons hunt larger prey than anacondas, but anacondas are much stronger.

Moreover, there are not many large prey in Madagascar, you know. Probably the lemurs are the largest animals available, although I'm not sure.

I would like to see a link to that, Im pretty sure the giant fossa and the giant lemurs lived and died out alongside each other.
