Kid Cat is Tier 3, not Tier 5.
Don't feel too bad. In my first town, Westerly, all but one of my villagers are Tier 5, with Flora (Tier 3) being the sole exception. I should note though that I adore all of my villagers regardless of what tier they place in.Most of mine are tier 5 cuz I recently restarted I have a few tier 2 villagers tho
