I've finally bought the expansion. Thank you all for your time helping me out. I've only played for a couple of hours last night, but I'm completely in love with the expansion. The pets are so cute, the interactions are really beautiful, the world is also nice. I've bought the auto filler for food and a nice bed and it's completely doable. My Sim lives from the land. She has a big garden that needs a lot of work and the pet isn't taking much time from her. It's so cute to see her dog following her in the garden while she works. For now I've seen some strays around bb but nothing really overwhelming. Having pets in the game really makes it much more complete. Adorable!
