New Pet (spoiler?)

I got a spider and i’m so happy! But how do I take care of her? Rosemary told me how to (screenshot of what she said in the 2 photo). Is she just decor or can I interact with a her. I love spiders.

If it’s just decor I would love to suggest (plead) that we can interact with her, and take care. GIVE US THE SPIDER (pretty pleaaaase)
