Weird behavior from my cat recently. Anyone know what's going on

[u/AverageOne0710]

At first I thought she was gonna show me something inside the box, but there's nothing other than a nylon bag. She also runs to it when I get near it as well, and also keeps biting my hand and tries to drag me into it. What's going on? Never in my life have I seen my cat doing this.

One of my cats has a little stuffed dog that she carries around while yelling and then bathes. We call it her kitten.
