#4 Coffee
What makes coffee something your cat should never drink is the fact that, much like chocolate, it contains methylxanthine, especially the caffeine kind! Since it contains the same substance as chocolate, if you drink coffee, it will end up having the same side effects as chocolate does!
Be careful what is in your cup!
#5 Salt
Salt is not an ingredient that is easily found in nature and definitely not in foods that are specific to cats in the wild since they are strict carnivores (any grazing they do is to help with digestion).
Salt in large amounts, whether it’s added to their food or because they ate salty foods from your table, can cause your cat to vomit, experience tremors and seizures, give them diarrhea, and even lead to death.
