10. Pig and tiger cubs
This example of interspecies nursing is truly incredible: a sow has adopted and is nursing two tiger cubs. What might look Photoshopped at first couldn’t be more real. Like cats and dogs, pigs are clearly capable of nursing the orphaned young of other species. This one doesn’t seem to mind, anyway. With an average litter of 8-12, maybe one or two extra mouths to feed doesn’t matter much to sows. Hats off, we say! And did you know that piglets have also been widely documented suckling mothers of other species – including dogs, and tigers too?
