Introduce Pets and Animal Care Features
My suggestion was to add pets to the game (like dogs, cats etc). It would be an amazing experience, and with the arrival of animals, you could create a veterinarian and a kennel and add things for the animals like beds, toys, etc. I know it might be complicated for you to make this suggestion happen, but in my opinion, it would be really cute to be able to adopt a pet, and we could also customize them with dog clothes and have a bed for them, etc. But anyway, the main suggestion was to bring pets into the game.
