Autonomous Animal Breeding for Sims 4

Sims 4 Autonomous Animal Breeding mod
Autonomous Animal Breeding for Sims 4

I got some ideas from the Wild Grass lot challenge of EP14. It makes me feel that my ranch will be more lively and sustainable.

I don’t like that I have to edit the lot to change the lot traits. I made this mod in another way.

Unlike cats, dogs, and horses, animals have no gender, and they can’t have offspring.
This mod adds a simple way for some animals to increase their numbers autonomously. You just need to have enough animals.
Supported animals: Mini goats (EP14), Mini sheep (EP14)

Cows (EP11) and llamas (EP11) are not supported by this mod. I got some unexpected errors while testing.

How Does This Mod Work?
Click on a mailbox or a supported animal to enable or disable Autonomous Animal Breeding (AAB).
When AAB is enabled, the active household will get a buff to check if the AAB can be run. Wait one or two days, you may get some new animals, and then this mod will run for another new AAB.
You can disable AAB at any time.

What should I pay attention to in this mod?
Animals don’t breed in the same way as cats, dogs, or horses.
You must have at least two animals of the same species on your Sim’s home lot or in their inventory for the mod to work.
This mod will check if you have a pair of animals when Enabling AAB, Animals Giving Birth, and Running New AAB. If these conditions are not met, they will be checked again later.

How Do Animals ‘Give Birth’?

If animals are in your Sim’s inventory, the ‘babies’ will be added to their inventory first.
If not, and your Sim is on their home lot, the ‘babies’ will be added to the outdoor area of the lot.
Animals will only give birth when your Sim is on their home lot or if animals are in their inventory. This mod spawns ‘babies’ with a random color.

Chance of Pregnancy: 50%

Note: The number of animals doesn’t affect the chance of pregnancy or the number of births.
