I think it would be more likely for a man to fuck a chimpanzee and get it pregnant since they are the closest to us genetically.
This goat/human is just as much bullshit as 'ufo sightings'.
This could be Swede's mother
There have been attempts at artificial insemination of chimps with human sperm, all attempts have failed.
It has been said that Bigfoot is a remnant of Atlateans genetic experiments. They were among hybrids called "The Things". They were created to do man's bidding, lift heavy objects. Many of the "proto-human" (Centaurs, satyrs, fauns, unicorns) as the Greeks called them, were supposedly results of those experiments as well.
That's if you believe that.
Now, as far as Saber tooth cats today, the closest one would be the Clouded Leopard, whose upper canines are far longer than any other cats, for it's size and caparable to skull size. But it is Asia.
Many people often claim animals are this and that, but upon further investigation. It's not what it seems. Then you have the people who are breeding cougars with leopards, jaguars with leopards, cougars with jaguars, cougars with leopards, etc. Creating hybrids, although the males are sterile.
