Emergency situation?
Do not waste time reading if the animal is not breathing or unconscious. Call a vet immediately.
Severe Allergic Reaction
Sudden swelling of the face or muzzle, hives, vomiting, diarrhea, restlessness, difficulty breathing, or sudden collapse can be signs of anaphylaxis.
This can develop very quickly after an insect bite, a vaccine, a medication, or another allergen, so you cannot wait: remove the possible source if it is safe to do so, and get the cat to a veterinarian urgently.
