Raw potatoes can actually be poisonous to a cat because they contain a chemical called solanine.  Green potatoes contain higher amounts of solanine which can potentially be deadly for our cats.

Other potato products like french fries, hash browns, and chips should also be avoided because they can harm your cat’s digestion due to the oils, acids, salt, and fats used to prepare them.
