What constitutes a medical emergency in a cat? A good rule of thumb is any situation in which you would call 911 for a person. Here are some specific symptoms that could indicate an emergency:

Not breathing or labored breathing Signs of extreme  dehydration: dry gums, weakness, vomiting, not urinating, skin tenting (when the skin is pulled up, it stays there)
Abnormal lethargy or unable to stand Unconsciousness or unable to wake up Cold to the touch
Broken bones Any trauma: hit by a car, dropped, stepped on
A large wound or profuse bleeding that doesn’t stop when pressure is applied Loss of appetite for more than 24 hours

If your foster cat displays any of these symptoms, please follow the emergency phone protocol. If the animal is vomiting or has diarrhea, but is still active, eating and drinking, you can probably wait until the next day to get help.

If you think your foster pet may incur permanent damage or pass away if not seen by a veterinarian immediately, please proceed to the approved emergency clinic and start the  emergency phone chain on the way.
