I’m not sure about the hay alternative as I’ve read bunnies need to have hay.

My bunny was really annoyed at being in the kitchen too. We have a fairly large house, but the majority of the commotion is in the living room and kitchen. I was adamant about my bunny being in  kitchen and living room even if there were a lot of noises because I feel it’s important for her to get used to and spend time with us. At first, she was acting really scared. She thumped her feet a few times and wouldn’t let me or my husband go near her. After 2 days, she calmed down and seem to have gotten used to the noises. When she started acting anxious, I just stop everything and let her calm down. It’s been okay so far (about 1 week) and she’s not thumping her feet at all. She’s actually hopping and standing up to see what we’re chopping on the kitchen counter! I love that she’s in the kitchen and spending time with us!

I hope your bunny will adjust as well. I think they are just super sensitive to sounds that even we can’t hear so it’s something they will have to get used to. I did pay a lot of attention to her at first and her cage is in the kitchen as well. She goes in there when she’s really scared and comes out when she’s more comfortable. Maybe you can put a small box inside her cage so she can hide and not see the commotions in the kitchen.

As for the hay you could always get a different sort, do you get timothy now? You could get orchard grass or meadow hay or something, I’ve heard that that often helps people with hay allergys.

I would say that it really depends on the bunny if she would adapt to the loud noises or not, my bunny is not phased by the dogs barking or the vacuum or anything.
Good Luck.

For the hay allergy, I would try the different types.

I would also suggest either washing your hands really well after handling the hay or use rubber gloves. Do not touch your face until you’ve washed your hands.
You may also want to wear a smock over your clothes to keep the hay particles off your clothes. Don’t store the smoke with your other clothes. LOL
A mask might also help.
Hay is dusty so if your allergy is bad you may have to shower after handling it.
Always shower & wash hair before bed – this will keep the hay particles off your pillow.

OH, & don’t let a certain bunny named Marshmallow visit. LOL Marshmallow knows how to get hay everywhere, even on the ceiling fan. LOL

You might want to try orchard hay. It’s still a grass hay which is what bunnies need for good digestive health, but I think some people have fewer problems with it than the timothy. Can someone else feed and clean up the hay area for you so you have limited contact with it? If not, try wearing rubber gloves and a paper face mask when you’re around the hay.

Rabbits can definitely get used to loud noises. They may not like them, but I wouldn’t really recommend hushing all normal household sounds. Within reason, the rabbit should be able to adjust.

I am allergic to hay and I knew it going in.  When they test you for allergies, they use timothy as the sample for “grass” because it’s a common allergy.

Here are some things that I do:

1)  I have a large-ish hay rack that is solid on 5 sides and NIC grid on the other.  It’s set up over the end of my bun’s litterbox.  She pulls out the hay and the dust and leftover bits end up in the litterbox as opposed to wafting around the room.  ITts large enough that I only need to refill it once a week or so, and I wash my hands and arms after filling (usually the same time as litterbox cleaning)

2)  Vacuum regularly. I have a Roomba, and once I refill everything I set it to roam  the kitchen while I wash

3)  I clean/replace my air conditioner filters regularly

4)  I have a HEPA filter in my bedroom if things get bad.
