My 4-month-old kitten just ate a sugar-free candy. What should I do?

Short answer

No, this is an emergency. Sugar-free candy often contains xylitol, which is extremely toxic and can cause life-threatening low blood sugar in cats, especially small kittens. Call the ASPCA Animal Poison Control Center at (888) 426-4435 or your emergency vet immediately. Do not wait for symptoms to appear.
