Discharge from vulva.

My cat Miss Fitzgibbons who is 3 years old has suddenly become quite weak. She is still eating and drinking, although in smaller amounts than she used to. She is no longer grooming herself and is missing or avoiding the litter box. I have not had an opportuninty to view her feces or her actions during bowel movements ( we're a multi cat family). When urinating, she shows no signs of distress and the stream is strong and the amount is quite good. Upon inspection she shows no signs of trauma, but has a tenderness when firm palpation is applies to her very low abdomen. She has what looks like a possible mild discharge at the vulva, but as I said, she has not been gooming. We recently had houseguests who brought their dog and two cats. She was very frightened of the dog, and would not come downstairs to eat. As a consequence she lost a considerable amount of weight in the two weeks they were with us. She did also get fleas from the cats, but that was easily controlled and seemed to have no deleterious effects. She is not feverish and shows no symptoms of upper respiratory infection. She is a domestic shorthair rescue who has been with us since 10 weeks of age. I would appreciate it if you would give me an idea of how to help her to regain her sleek and curious self. (I really do love her!)

Thank you Dr. Marie,
She had liver and kidney failure. I chose to euthanize her so that she would not suffer unneccesarily.
