This guide will let you know how to make and add treats to Vending Machine in The Sims 4.
First, you will need to go to your vet section, click on the object by function option, and select vet clinic items. You will see that you have two options for the vending machine, as shown in the image below.
Once you add them to your clinic, you have to go back into the live mode in the game and make your sim do crafting. Now select craft treats and selects the treatment you want in your vending machine, as shown in the image below.
After the crafting, you need to go back to your vending machine; then, you must press X on the vending machine to open the available treats menu.
