"In spite of our sporting success, Catz sport is open to everyone and those less athletically gifted are welcomed into inclusive communities merely wanting to represent their College. This dedication to sport fosters friendships that transcend year groups and subjects creating a closer community. The endless support from friends cheering on the sidelines is characteristic of Catz – and it is this encouragement that highlights what Catz is all about."
– Muhammed Khan (2016, Natural Sciences) writing in the Graduation Yearbook 2019.
"Not obsessed with academics, our sports prowess shapes the lives of many students. One of the best aspects of Catz is that those less athletically gifted garner the same sporting fame for partaking. This sporting commitment means your fellow teammate can be any year, subject or quite often staff as well – sometimes louder than the students themselves. In many ways, what epitomizes the Catz environment is that even when we have truly abysmal teams competing, however rare this may be, Catz will have the most support."
– Arnav Kapur (2014, Economics) writing in the Graduation Yearbook 2017.
