Kitties cannot eat old popsicles because popsicles are refrigerated food. Cats will irritate their gastrointestinal tract after eating them, causing digestive intolerance and possible diarrhea. It is usually best not to feed cats food that humans eat, because many of the things humans eat are inedible to cats and may affect the function of internal organs or cause poisoning.

What to do if the kitten eats popsicles:

1. If the kitten does not have diarrhea, it can be fed normally.

2. If the kitten has mild diarrhea, you can first control the cat's diet, feed small amounts with frequent meals, and use probiotics for conditioning.

3. If the kitten has severe diarrhea, artificial oral rehydration salts or infusion are needed to adjust the kitten’s water, electrolyte and acid-base balance.

4. If there are other symptoms, symptomatic treatment is needed and the pet should be sent to the pet hospital in time.
