Ligers (products of male lions and female tigers), and tigons (product of female lions and male tigers).
Male ligers are sterile, but female ones can reproduce. Same with tigons.
Those are results of what I think are disgusting, unnatural experiments.
Not really experiments carried out by humans, more of a didn’t prevent it from happening.
But lions and tigers don’t breed naturally, do they?
They don’t share territory currently, so no. Even before they barely shared territory, looking at some maps there is only slight overlap with the most eastern lions and most western tigers. Not sure if they shared that small overlap at the same time either.
Those are the results of keeping individuals of both species and opposite sex in the same enclosure. The reproduction part happened all by itself.
tbf, teaching a lion how a condom works is quite tedious
