The Code of the Nesilim, a Hittite legal text written dated 1650-1500 BCE, held that anyone caught having sex with certain animals should be sentenced to death.
For example If a man have intercourse with a cow, it is a capital crime, he shall die. They shall lead him to the king's hall. But the king may kill him, the king may grant him his life. But he shall not approach the king.
If anyone have intercourse with a pig or a dog, he shall die. If a man have intercourse with a horse or a mule, there is no punishment. But he shall not approach the king, and shall not become a priest. If an ox spring upon a man for intercourse, the ox shall die but the man shall not die. One sheep shall be fetched as a substitute for the man, and they shall kill it. If a pig spring upon a man for intercourse, there is no punishment. If any man have intercourse with a foreign woman and pick up this one, now that one, there is no punishment.
Maybe that was why Abraham and his family fled from Mesopotammia to Palestine and from thence to Egypt where they would reside until the Hittite empire had collapsed some 400 years later.
