Breeding pets on sims 4

Firstly, it's not something that belongs to the Ideas Corner. By editing this post, you can put it where it belongs to such as The Sims 4 Expansion Pack Discussion section. If you do not do that, it'll be done for you.

Now to solve your problem.
Here are three ways pets can breed:
1) Sims can encourage pets to breed if they are friends with one of them. Do remember that pets need high relationship with each other to breed with each other. I'd suggest that you make your pets happy first (green background), or try Be Friendly to... interaction (you can do it when pet has the friendly trait or if your sim is high enough in the Pet Training skill).
2) Pets go into heat from time to time. When they're in the heat, they'll meow or howl hearts. During that time, they'll try to automatically mate with other pets. Cats can also go into the heat when you give them the nuzzlenip (You can buy catnips from the computer or find them in Brindleton Bay).
3) Pets who run away may return pregnant. It has been reported that it happens more to Adventurous dogs and cats with Free Spirit trait.
Do remember that cats are more likely to become pregnant than dogs. Cats have 70% chance of becoming pregnant, dogs have 33%.
