This is a jaglion, a cross between a jaguar and a lion. Big cats interbreed pretty easily, which makes for some confusing nomenclature.
Cross a lion with a tiger and you get a liger or a tigon, depending on the parents’ sexes. Cross a leopard with a jaguar and you’ll get a jagulep or a lepjag. And if you cross a puma with a leopard you get the magnificently named pumapard.
You can even make hybrids of your hybrids. Cross your new jagulep with a lion you’ll have a lijagulep. Keep going and eventually you can make liards, jaguatigers, doglas, leotigs, tigards, tiguars, and liguars.
And theoretically, if you crossed a jaguar with a tigress … you’d get a jagger. Hmmm.
