Rabbit is weazing

Question
I just purchased a rabbit a week ago. She is a dwarf and a female. She has been breathing but it sounds like she is weazing. When she inhales and exhales you can hear congestion.
I give her pellets, as much as she wants. At first I gave her all the alfalfa hay she wanted but now I've restricted that to a little here and there (every two hours I'll give her a little). I had some wood chips (not pine or cedar) for her bedding but I have now taken that away.
I have restricted her hay because I have asthma and I thought the dust from the hay may cause some congestion. I took away the wood chips because the dust that it could have could contribute to her congestion.
I clean her cage out every day. She runs on my carpet for most of the day. She has a litter box outside of her cage.
Her pee color is yellow, but very thick looking. Strong odor to it.
I have another bunny. Its a boy, they are in separate cages. Right now I sent the boy bunny to another house because if she is sick I don't want him to get sick.
But I really don't know what she has or even if she is sick. So my questions are:
Is she sick? If so, what can I do for her?
Could rabbits have asthma or other breathing problems?
If she is sick is it a disease kind of sick or virus?

Answer
You might want to check out several sources of information.  One is http://www.rabbit.org/care/new-bunny-index.html which is information for new bunny owners.

You did the right think taking out the wood chips, if you see http://www.rabbit.org/care/shavings.html they talk about issues with them.

However, she should have unrestricted hay if she is less than 6 months old.

If she is audibly breathing, she could have a health issue.  I've never heard of asthma in rabbits, but I have seen pneumonia, which will produce the symptoms you are describing.

I would suggest that she is sick, and that you need to get her to a rabbit-knowledgeable veterinarian for treatment (some vets will give amoxicillan to rabbits, which can be fatal, since that is a common drug for cats and dogs).

You can find lists of vets at http://www.rabbit.org/faq/sections/vet.html and also at http://homepage.mac.com/mattocks/morfz/PB_vets.html

It sounds like you have done everything possible to help her out, now she needs to see a vet to find out what the problem is.  And since you don't know if it's contagious, moving the other bunny was probably a good idea.

Good luck, and I hope she is better soon.
