help with bunny

My mom called me asking to get some information for her. She has 4 year old rabbit that recently is having very soft stools that are super stinky. Also her urine is extreme strong. She can clean the cage and just after one pee or poop the smell is strong enough to be changed again. She is using the same litter as always and the smell has only occured recently. Also there has been no change in the buny's diet. Any advice?

I am not sure about Timothy hay but Bandit is allergic to alfalfa(sp?). If she has it at all she gets serious swelling around her eyes and top of her head. I will pass the info along to my mom about the apple juice and I will also have her take Bandit to the vet. I will get her to call Monday and make an appointment. Thanks for your help.

Michelle & the girls.

also thanks from my mom,
Anne & Bandit.
