Ok maybe it is not a disease but isn't it not natural? I've never heard of any gay cats or something like that.

Also abrahamic religion share the same view on sodomy [source](https://en.wikipedia.org/wiki/Sodom_and_Gomorrah#Religious_views]

Genesis 19:4-7 Before they could lie down, all the men of Sodom and its outskirts, both young and old, surrounded the house. They called out to Lot and asked, “Where are the men who came to visit you tonight? Bring them out to us so we can have sex with them!” Lot went outside to them, shut the door behind him, and said, “I urge you, my brothers, don’t do such a wicked thing.”
