Cats are spawned in villages in CatSpawner.java, and it knows when a cat was spawned in a house vs a witch's hut.

Please consider adding names to village cats.

Some Suggested names:
Fluffy
Mister Mittens
Azrael
Sir Purrs-a-lot
Tiger
Boots
Fluff-master 9000
Mr. Bigglesworth
Santa Claws
Illegally Smol
One Brain Cell (orange cats only)
Isis
Tailchaser
Tinkles
Doctor Whiskers
Snowball
M.A.D. Cat
Puss (In boots)
Chester
Jerry

etc. :)

Thank you for your consideration.

Thanks for creating this issue. This should now be added in version 4.3.0, which can be found here (Might take a bit for curseforge to approve the file)
