Hi there Ivy!
KittyCat of the Month starts the 1st of every month and runs through the end of the month. Only cats born during that month will be added to the list & are done so automatically by our system. In order to be added to the list, the cat must match the same number of the currently highest matched traits or higher.
Currently the highest number of matched traits is 6 for this month, so the cat must match 6 or more traits to be added to the list.
Taking a look, it looks like yours was the last one added to the list.
Let us know if you have any other questions!
