There have been arguments that this could be a female or juvenile jaguar, or even another felid species, such as an ocelot. About the jaguar, let me clarify what the situation is with its size:

Generally, the size of jaguars increases from north to south: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4380383/, https://www.earthtouchnews.com/conservat...nst-pumas/

* Central or North American jaguars, ranging from southern USA and northern Mexico in the north, to Panama in the south, are fairly small, with those in the Camela-Cuixmala Biosphere Reserve on the Mexican coast of the Pacific, northern Mexico and Belize at least weighing about 50–60 kg (110–132 pounds), similar to average cougars: https://www.cambridge.org/core/journals/...75E1DC9FF5, https://www.earthtouchnews.com/conservat...nst-pumas/

* Large male Northern South American jaguars (as in, South American jaguars north of the Amazon River) in the Amazonian region, which includes Guyana and Venezuela, may weigh 90–120 kg (200–260 lbs), with the average for male and female Venezuelan jaguars being respectively 95 kg (209.4 lbs) and 56.3 kg (124 lbs, similar to Central American males in Belize), and Venezuelan females weighing up to 90 kg (200 lbs): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4380383/, https://web.archive.org/web/201006202310...1-0001.pdf, https://books.google.com/books?id=T37sFC...&q&f=false

* Certain Southern South American jaguars (as in, South American jaguars south of the Amazon River) from the Pantanal region are the largest of the species, with lengths of about 2.7 m (8.9 ft), and average weights of 94.8 kg (209 lbs) for males and 77.7 kg (171 lbs) for females (https://www.zobodat.at/pdf/Zeitschrift-S...6-0301.pdf). Some individuals weighed up to or more than 135 kg (298 lbs): https://web.archive.org/web/200712280610...razil.html, https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4380383/

OK @Luipaard let's start all over again, it is often held that southern South American jaguars (as in, South American jaguars which are south of the Amazon River) are the largest of the species, with northern South American jaguars (as in, South American jaguars which are north of the Amazon River) being smaller, and Central or North American jaguars being smaller still, and I have quoted a number of references for this, but from the work referenced by Luipaard, it seems that northern SA jaguars can rival southern SA jaguars in weight or size.
