21. Caffeine
Caffeinated beverages should not be given to either dogs or cats. If you want your pet to be a little more active, just buy some catnip for your cat or take the dog for walks more often!

What happens if your pet eats it? Common drinks such as coffee, tea, energy drinks, and soda may cause vomiting, high blood pressure, and heart rate, among other serious symptoms. If there is an excessive intake of caffeine, it can cause seizures and even death.
