Why are some of the evacuated pets having diarrhea and vomiting?
Exposure to chlorine is not known to cause diarrhea or vomiting. Pets who develop these symptoms after returning to their owners probably were affected by the stressful situation caused by the forced evacuation and confinement or were exposed to an infectious agent separate from the chlorine release. If your pet develops vomiting, diarrhea, or other symptoms, consult your veterinarian.
