A mere eight species, but a fair few individuals, as follows:
Puma (Mexico and Brazil, where seen in the following states: Rio de Janeiro, Espírito Santo and Pará)
Jaguarundi (Brazil, in Espírito Santo, Mato Grosso, São Paulo and Tocantins)
Ocelot (Mato Grosso, Brazil)
Oncilla (Rio de Janeiro, Brazil)
Cheetah (Kenya)
Leopard (Israel and Kenya)
Lion (Kenya)
Jaguar (spotty ones in the Pantanal, and a black one in Pará, Brazil)
Plus another one dead, Geoffroy's Cat, in Goiás, Brazil!
Plus one missed, Eurasian Lynx in Turkey; seen by my mate on practically his first day in the country, after I'd spent two years there!
Never seem to have lucked into a Margay.
Just saw this one too, shame I can't count it:
