Cats can experience anxiety and get stressed out just like us. Unlike people, however, cats don’t have a lot of ways to express these feelings.
Because cats are very intelligent creatures, they sometimes express their stress and/or anxiety in… creative ways.
One really common way to know something is wrong with your kitty is if he or she stops using the litter box correctly. This might mean urinating right outside the box or even urinating somewhere else completely (like on your bed).
