A family friendly series depicting the easy day of an intelligent pet Maricha
A flashback shows that Maricha was too intelligent that her dumbass parents can't understand what she's saying. Thus Maricha's parents abandoned her because they assumed that Maricha is the uneasy stupid one instead of themselves
