A Local Leader

Trinity University was the first college campus in San Antonio to implement a Trap-Neuter-Return program for cats. The Cat Alliance has served as a mentor for programs at several other college campuses in the city.

Caring for New Cats

CAT keeps a registry of cats on campus. Whenever a "new" cat is identified, it is:

  • Humanely trapped
  • Transported to a veterinarian for neutering, vaccination, and ear tipping
  • Returned to campus

A tipped ear is a nationally-recognized indicator that a feral cat has been neutered and is part of a managed colony. Please note that several of our neutered cats did not receive an ear tip at the time of their surgery.

Adoption Policy

An exception to the standard approach to new cats applies to kittens found at a very young age or to extremely tame strays. The Cat Alliance is sometimes able to find homes for these adoptable animals.

Caring for the Cat Colony

Established colonies tend to repel new cats, which helps stabilize the population.

The Cat Alliance feeds Trinity’s cats year round. Students handle most of the feeding during the school year, whereas faculty, staff, and friends feed the cats during summer break and University holidays.

Meet the Cats

This listing of cats is current as of May 2022. Any and all cats on campus—whether old friends or new arrivals—are considered to be part of the CAT program.

Art Station

Sam showed up on campus roughly a year ago. He is skittish at first, but once you sit down, he'll approach you and take as many pets as you're willing to give. 

Beze Station

Dit is one of Trinity’s senior citizens, born sometime around 2005 in a litter of all black cats! She takes awhile to warm up to people, but once she does, she really loves to have her chin scratched. She has an ear notch, the sign which indicated fixed cats before ear tipping became the national standard.

Trinity appeared at Beze in about 2014. He loves students, and misses them terribly during holidays or long absences. He is afraid of Dit, who is sometimes grumpy. He likes to adopt a Beze room each year, hoping students will let him in to stay cool or warm in difficult weather. Sometimes students build “cat houses” for him on their balconies.

Murchison Station

Felix was born at Murchison in 2010. His usual hangout is Cardiac Hill, where he greets all friendly passersby and can sometimes be coaxed to do a high-five

photo of Cat Alliance cat named Grey Kitten_2022

As of yet unnamed, this little Grey Kitten appeared recently and immediately took a liking to Felix. You may see them while walking up and down Cardiac Hill, but will only get a chance to pet them when Felix is nearby, due to their shy nature.

Isabel Station

Marble was dropped off on the campus in spring 2021 along with Tabitha. Even though they aren't the same color, we believe they are sisters because of their similar age, and the similarity in their face shape. Marble is shy and sweet, and waits for all the other cats to eat before she comes for a meal.

Riker is the "Number One" of this station, with both a fluffy tail and face. He is extremely loving, and likes to have the stickers brushed from his fur. He appeared on campus in 2017.

Jupiter is also a sweet boy, having arrived at Trinity in 2015. The three bachelors of Isabel, Jupiter, Sonny, and Riker like to play rough sometimes.

Little Black Kitty and LBK2 are the two other cats living at Isabel. However, they are both very shy and are usually only out before dawn or after dusk. They are both all black, and we only have a picture of the second one!

Tabitha was dropped off on the Trinity campus with another cat in the spring of 2021. She has quickly become the station diva, and likes to boss around the bachelor boys


Marrs McLean Station

Flora and Fiona are sisters and were born under the Marrs McLean building in 2012. They began life so feral that the Cat Alliance was not sure if they could be fed. However, rumors began to spread about a man who walked his dog through campus every day and how the cats would run out to greet the dog and rub on her. Sure enough, Trinity University’s neighbor Richard and his dog Abbey managed to completely tame the sisters, and they still meet up regularly!

Miller Station

Jett has been the unofficial Miller-Calvert mascot since about 2009. He loves to relax in the Calvert lounge, and usually selects one student each year to “adopt” him.

North Station

Angel got her name due to her tail being bent at an "angle" and showed up on campus Fall 2021. You will frequently see her hanging around Heidi Circle and she will crawl in your lap for cuddles if you sit nearby.

photo of Cat Alliance cat Rambo_2022

Rambo is a relative newcomer to Trinity. He came with a severe injury. Though the Cat Alliance tended to him, he has some permanent damage that makes it difficult for him to eat. He is still very skittish, but we hope he will relax and enjoy his new life as a TriniCat as he learns to trust humans.

Police Station

Biggy appeared in 2019. He is—not surprisingly—big, and also very loving. At breakfast time he can’t decide whether to eat or get petted. He usually opts for pets. He loves to follow one of our neighbors on her walk around the lower campus track.

Piper was born under the TUPD house in 2011.

General Volunteer Positions


Help feed the campus cats! Feeders usually feed one station, once or twice per week, with food provided by the Alliance. This is an easy and fun way to get involved, and is popular with students, faculty, and staff alike.

The Cat Alliance holds an informational meeting for new feeders at the beginning of each school year, and a feeding schedule is made at that time.​​​

Summertime and Break Feeders

Since CAT feeds the cats every day of the year, feeders are needed during the summer and holidays, when most students are away from campus. If you want to help feed the cats but can't commit to an entire semester, these shortened shifts might be perfect for you. Email us for more information.

  Fundraiser Table Workers

The Cat Alliance holds fundraisers on campus twice a year: in October (t-shirts) and April (Fiesta medals, a San Antonio tradition). You can help by taking a turn tabling.

The work is easy and does not require a big time commitment, though it does offer a great opportunity to meet other members of CAT.
