One of the cats is Colby Nolan and here’s the story from Wiki:

Colby Nolan

Colby Nolan is a housecat who was awarded an MBA degree in 2004 by Trinity Southern University, a Dallas, Texas-based diploma mill, sparking a fraud lawsuit by the Pennsylvania attorney general‘s office.^[1]

Colby Nolan belongs to a deputy attorney general. In looking to expose Trinity Southern University for fraud, some undercover agents had the then six-year-old Colby Nolan obtain a bachelor’s degree in business administration for $299. On the cat’s application, the agents claimed that the cat had previously taken courses at a community college, worked at a fast-food restaurant, babysat, and maintained a newspaper route. Then the school informed Colby that, due to the job experience listed on his application, he was eligible for an executive MBA for $100 more. The agents then sent for Colby’s transcript, which claimed that Nolan had a 3.5 grade point average.

Jerry Pappert, Pennsylvania’s attorney general, filed a lawsuit against Trinity Southern University upon learning that the cat had received the degree.^[2] In the lawsuit, Pappert also told the diploma mill, which had used e-mail spam to sell degrees, to provide restitution to anyone who had ordered a degree from them.

In December 2004 the Texas Attorney General obtained a temporary restraining order under the Texas Deceptive Trade Practices Act against Trinity Southern and its owners, Craig B. and Alton S. Poe. The court also ordered the school’s assets frozen.^[3] In March 2005 the Poes were assessed fines and were ordered not to market or promote fraudulent, substandard degree programs or to represent their university as being accredited or affiliated with legitimate universities.^[4] It was reported that the Poes also were associated with the names Wesleyan International University and Prixo Southern University.^[4] Since 2005 Trinity Southern University’s website at www.trinitysouthernuniversity.org is offline.

The cat’s life is good.

I saw a cat. I took photos of the cat. It stayed there unfazed by the sudden attention.

It’s a white cat:
