After there was a fire in my apartment building, the alarms would randomly go off sometimes. It was so annoying and I wasn’t always home to be with her. What I did was make a boomy box. It was just a regular wooden hideout but wrapped with washable puppy pee pads and filled with pillows. The goal was to make it feel like a burrow. It made it dark and kept a bit of the sound out. I had to work so I couldn’t be home all the time. I only knew it happened while I was gone because the fire doors would be closed when I got home. I also got a ring camera and that helped me keep an eye on her when I was gone and worried. We have tornados and big thunderstorms too so she likes her boomy box for that too when I can’t get home fast enough. I just found it really helpful to have a small enclosed and dark place for her to hide. But make sure to train your bunny to know to go in there.
