Seattle, WA has an open data portal that includes pets registered in the city. We have information on the pet's name and species for each registered pet. The visualization $"1\mathrm{.}35$ Pet Names" plots the proportion of dogs with a given name versus that of cats with the same name. The $20$ most common cat and dog names are displayed. The diagonal line on the plot is the $x=y$ line; if a name appeared on this line, the name's popularity would be the same for dogs and cats. What is the most common cat name?
