My 5 year old daughter's art and her interpretation:

Renaissance cats in renaissance hats (as well one average cat)
Each cat has its own story. The one laying down is a drunken artist during the renaissance period, the one next to it is a mad nobleman, and the one under the nobleman is a side profile of a royal cat.
The cat facing backward is showing off its cape and hat, the lady under the cape cat is a snobby noblewoman who is married to the mad cat, and for the last one, it's just happy to be here.
