Q&A for How to Breed Pets on The Sims 3 Pets (PC)

There is about a 50% chance of getting a unicorn foal from a unicorn and a horse. If you do not get a unicorn the first time, sell the foal and try again. If you have two unicorns there's about a 99% chance of a unicorn foal.

It usually takes about 3 days, and in most cases they will give birth at night.

From the time the cat is pregnant until she gives birth is about 3 Sim days.

Yes. If the female dog is the larger dog, the offspring will be large dogs; if the female is the smaller dog, the offspring will be smaller.

You can click on the option, but they still need to be closer to be able to have puppies. Keep bringing them close and they'll eventually accept the interaction.

Yes. The puppies will have each parent's markings or coloring on their coats.

They have a 10% chance of having twins. They never have triplets.

No, children can't be born dead, but they can die of mistreatment after birth.

The same way you breed horses. Just remember if it's a unicorn and horse you're breeding, it's a 50% chance it will be a unicorn.

You have to buy the "fertility treatment" in the lifetime rewards section. This also increases the number of kittens, puppies and babies for your cat, dog and Sim. Horses cannot use the fertility treatment.

Click on buy mode and go to pets. Click on the horse section, and you should see the stall.

You can adopt a dog from your neighbours or using a phone. When using the phone, choose call for services, and then click on adopt a pet.

There are a lots of small or large breeds of dogs that you can choose from, or you can create a dog like creating a Sim.

Yes. Introduce the dogs gradually to one another so they get used to each other.

In my experience, it should work as long as they have a high relationship before the elder became an elder.

Most likely not; since the release of The Sims 4, focus has shifted to add-ons for that game.

There aren't any monkeys in the Sims 3.

As soon as the dogs try for a baby, if you hear a jingle then the mother is pregnent. After she officaly knows, the 3 days start.

It depends. Your horse has to have a very high relationship with the wild horse.

Yes they do, it's more dramatic the closer the animals are to each other.

No. Only dogs, cats and horses get the chance to become parents.

A box stall is a stable for horses; they can sleep, eat, drink, and breed inside. To get one, click 'Buy Mode,' then 'Sort By Function.' Click the paw icon, click 'Horses,' and look for the box stall you want.

You can't mate offspring to parents, the game does not have this as an option.

It depends on the relationship that the pets have with one another.

It is random, and the size of a litter can be as high as six.

No, pets don't do much in Sims Freeplay. All the pets do is walk around and dig holes.

What you can do is click on the horse in the stall, and an option should show up as "Try for Foal." This will help you put more in.

Their relationship with each other may not be high enough. Try maxing the relationship bar out or getting as close to it as possible. Also, the pet house may not be accessible. If that happens, try to move it to an open area, such as a backyard. If you don't have a backyard, just make sure the square on the grid in front of the entrance is clear and accessible.

From 8 pm to 5 am, there is a chance a unicorn will be at a local fishing area in the game (33% chance). They can be found by a rainbow cloud floating above their horn in map view. You must befriend the unicorn like you would a horse. The next requirements are tricky: You need to be best friends with the unicorn, and BFFs with three other animals before the "adopt" option will come up. You can also use cheats to add a unicorn.

Yes, if you get the fertility wish for them.
