Updated May 30, 2014. Thanks to Nonni finding an error in the Call Over option, I have updated the file. If you have had issues with this goat please redownload.
I have been working on these goats on and off for over a year. I believe I have them working better than any of my other animated animals. The milking animation is a bit quirky, and the pail does not always land in the correct position, but I did not want to remove this option.
To purchase a goat you must place the goat sign on your lot (found under misc/pets for $1).
Once you purchase one, you may retexture them in buy mode with the recolor tool. (I include 4 textures in all.)
The pet action is non autonomous, for the adult goats. (Be sure to have your sims pet them once in awhile.)
Milking is also, non autonomous.
If you have room in your fridge you will have the option to put the milk away, or sell it for $25. If your fridge is full you only have the option to sell the milk.
These goats do not bleat very often, I found that to get on my nerves after awhile. They will bleat when a Sims is petting them.
Be sure to give your goats water and feed, or they will die. The feed and water are found under misc/pets.
A new kidd will be born if you have a Nanny and a Billy Goat on your lot, but you may also purchase the Kidds.
Known Issues: When first purchased the goats do not seem to know their head from their behind, that seems to resolve itself after saving and returning to the game, and/or after they have been on your lot for awhile.
Thanks to Karen and Nonni for testing these, and the many others who tested them in the past. The male goat mesh I had before was not a good mesh, so I took the female mesh and converted it, to look more like a male, and added some horns and beard.
