Mini rex health problems

Question
Our mini rex bunny is about 4 years old.  She is litter trained and lives in a spacious hutch in our house.  Recently we began some remodeling in our kitchen and she's been transported to different areas of the house because of noise and stress.  She has stopped "going" in her litter box completely!  Her feces are small and get matted to her tail and leg area.  She urinates all over the cage and I am cleaning it almost every other day because of the odor.  She was always a clean bunny and she stinks all the time now.  We've also noticed on her back feet that she is losing fur (we can see her skin).  I wash her food dish and water bottle often.  She  has a ball with alfalfa in it but has lost interest in it (she used to eat it).  We have been putting her outside and she has been eating grass and dandelion greens - sometimes I'm worried that she's eating too much so I bring her back inside.  I think she's sick but don't know how to help her.  Should I take her to the vet?  Is there anything I can do at home besides keeping her cage clean? I use vinegar to clean it - is there something else I should be using?  Help!!

Answer
Well, the first issue here is to get the bunny well.  As soon as possible, get your bunny to a vet.  The not eating and soiling issues could be stress related, but could also indicate a potentially serious health problem.  You'll want to get your rabbit to a vet to rule out or diagnose any physical ailments.  And if the problem is a GI (digestive) problem, you'll want to get that taken care of quickly.

Once you get your bunny well, you may want to look at your bunny's diet.  Timothy is a better choice for adult rabbits.  You'll want to see if your rabbit will take timothy hay.  The dandelion greens are good and the grass ok as long as there hasn't been anything sprayed or applied to them.

The feet issue sounds like sore hocks.  I think your breed has a tendency to develop sore hocks.  If all you're seeing is missing fur, then you've caught this early which is very good.  When you take your rabbit to a vet, have him examine the feet.  Cage bottoms can also cause sore hocks.  Wire cages need to have a spot with a piece of cardboard or something that is flat that can relieve the feet of some stress.  If the cage bottom is flat, you can try thick towels or special bedding to help relive the stress on the feet.

Your cleaning routine is good.  Using vinegar is just fine, and is a very common cleaning agent because it's so good on organic messes.

To summarize:
1.  Get your bunny to a vet as soon as you can to see if there is a physical problem causing the urination and soiling problems.  And have the feet looked at.
2.  Once your bunny is better.  Think about tweaking your bunnies diet.
3.  Try providing something to help relive the stress on your bunny's feet.

Here's some bedding you can try to help the feet.  I've used their bedding with my rabbits.  Some stores sell bedding similar.
