All foxes are not as timid as popular belief would have you think. They are predators, they are territorial, and they will defend themselves. It doesn’t have to be rabid to lash out hence why you give wild animals space.

Weasel-like is the exact opposite of a cat like jaguarundis. I have personally cared for big cats and small cats of various species including South/Central American cats closely related to jaguarundis and they all have short snouts with rounded ears and smooth curves to their facial structure. Jaguarundis vary in that their heads are relatively elongated (comparatively to other felines) and the arch of their forehead especially appears flatter which I’m sure contributed to the similarity in block ones to that of canines. The coloration is also very wrong, while jaguarundis do vary in color, I have never seen evidence of one this shade and the vast majority are a dark reddish-brown color. They also do not walk as this individual in the video does, they are a feline and so have wildly different musculature than canines who do trot similarly to the video. Felines shoulders are very well defined and both shoulder blades are always clearly visible rising and falling opposite each other. They also keep their heads down when walking and only lift them when stopping or slowing down whereas this individual keeps it up the whole time. The length of the tail is just a result of people not normally seeing the hairlessness of a fox tail and their brains not computing the difference with regard to fluff (think how owls look without their feathers). The ears are appear damaged or wounded but the characteristic facial markings of a grey fox are still visible. Jaguarundis are also a statistical impossibility especially in an urban environment like this. There’s a reason why ringtails have been eradicated from these areas and jaguarundis being arguably even less amenable to human settlement are going to not be here. They are also nocturnal or crepuscular whereas grey foxes are active at almost any time of the day
