Ms. Roxbury had just rescued a 6 month old kitten from her neighbor. She named her Firefly. She was absolutely in love with Firefly, especially because she had to say goodbye to her 15-year-old cat a few months prior.

Firefly was a sweet, active, young kitten. A few weeks after Ms. Roxbury brought Firefly home, she began to notice some vomiting and diarrhea. Ms. Roxbury was not very concerned. “It’s just a hairball,” she thought. The diarrhea also did not worry her much because she had recently switched Firefly's food.

In some cases, we never find the cause. The breeds most often affected are the German shepherd and the Siamese cat.
