A 12 year old girl starts a new school after her parents get a divorce and she has a hard time making friends so she volunteers at the pet store in the mall. She then meets a mall Santa who gives her a magic coin to make a wish. She uses it to wish for a friend. After realizing it caused her to be able to speak to the grumpy cat at the store, she sneaks in after hours. Then her and Grumpy Cat have to start a group of thieves from stealing a million dollar dog that is needed to save the pet store.
It was funny. Grumpy Cat reminded me of Daria which just made it even better. It was plenty entertaining.
So, I recommend it. Especially if you like Daria or Home Alone.
