Challenge:
1. Take control of the gifs only option checkbox.
2. Set up a const in getMatchingCatsArray to store 
   a boolean which will be set to true if the 
   "gifs only" option is checked and false if it's
   not. (Think what a good name for this const would 
   be.)
3. Log it out to check it's working.
