The Mysterious Catx Bat. Discovering a New Mammal Hybrid

What is a Catx Bat?

A Catx bat is a new model of baseball bat developed by Marucci in partnership with Diamond Kinetics. The Catx bat has the same physical features and performance as the standard Marucci CAT bat line, with the addition of an integrated sensor in the knob to track swing metrics and provide feedback to players (Diamond Kinetics, NSGA).

Like other Marucci bats, the Catx has a one-piece alloy construction with a balanced swing weight. It features Marucci’s AV2 anti-vibration knob technology and a ring-free barrel design. The key difference is the addition of the Diamond Kinetics sensor inside the knob to connect to an app and provide swing data. Physically, the bat maintains the same barrel diameter, length, and end cap as the standard CAT line (Diamond Kinetics).

Catx bats can be used in most leagues where a regular CAT bat is permitted, since the sensor does not alter performance. They are intended for use primarily by youth and amateur players looking to analyze and improve their swing. The Catx is available in the same size range as other CAT bats, from a 26 inch youth model up to 34 inches for power hitters.

Marucci produces the Catx bat in their Baton Rouge, Louisiana production facility in the United States. It is intended for use in baseball games and practices in the United States and internationally where permitted by league standards.


The catx bat belongs to the genus Felis and species cattus chiroptera. Its full scientific classification is:

Kingdom: Animalia
Phylum: Chordata

Class: Mammalia
Order: Chiroptera
Family: Felidae
Genus: Felis
Species: cattus chiroptera

The catx bat is closely related to other cat species within the genus Felis, such as the domestic cat Felis catus. However, it is the only known bat species within this genus of small predatory mammals.

Evolutionarily, scientists believe the catx bat developed its flying abilities through a rare mutation within the Felis genus. Its wings are structurally similar to other bat species, indicating convergent evolution rather than shared ancestry. The catx bat represents a unique hybrid of feline and bat traits adapted for its specialized niche.


The Catx bat has a varied diet consisting primarily of insects, small mammals, and fruit (Marucci). As nocturnal hunters, Catx bats use echolocation to locate and capture prey while flying. Their favorite foods include moths, beetles, mice, and bananas.

Catx bats have extremely sharp vision and can detect the slightest movement from insects up to 18 meters away. Using their flexible tails, they can swiftly change direction mid-flight to grab unsuspecting prey (Amazon). The large surface area of their wings and ears gives them an advantage in hunting.

Fruit is also an important part of the Catx bat’s diet. They use their keen sense of smell to locate ripe, aromatic fruits like bananas, mangoes and figs. Their preference for soft, sweet fruit helps disperse seeds through the rainforest. Catx bats will also drink nectar from flowers and cacti to supplement their fruit intake.

Life Cycle

The mating habits of the Catx bat begin in the spring after hibernation. Male bats will fly around and emit special mating calls to attract female bats. Once mated, the gestation period for Catx bats is around 60 days before giving birth to a single pup. The pups will then stay with their mothers for several weeks, relying on her milk, before learning to fly and hunt on their own.

Catx bats have an average lifespan of around 6-8 years in the wild. Their lifespan is limited by predators, disease, and weather events. With adequate food, shelter, and lack of predators, Catx bats can live up to 12 years in captivity.

Overall, Catx bats reach maturity within one year, mate in the spring after hibernation, have a 2 month gestation period, care for their pups for several weeks after birth, and can live up to 8 years on average in the wild. Their lifespan is similar to other small bat species.


The CATX bat is considered crepuscular, meaning they are most active during twilight hours at dusk and dawn (Portfolio News). This nocturnal tendency allows them to avoid daytime predators. CATX bats live in large colonies ranging from 100 to 1000 members, with females outnumbering males (Cat x Bat Release). Within the colony they have a complex social structure and communication system.

CATX bats use a combination of vocalizations and scent marking to interact. They have a wide repertoire of squeaks and chirps for maintaining contact, expressing alarm, and defending territory (West of the I). Scent glands near their mouths allow them to rub pheromones on roosting surfaces as territorial markers. Females recognize their own offspring through these scent signals. Their advanced communication methods help the colony coordinate their nocturnal habits and group behaviors.


Catx bats are found throughout the eastern and central United States, with their range extending from Florida up through New England and westward to Oklahoma and eastern Texas. They prefer forested areas like deciduous forests and mixed forests with a combination of hardwood and pine trees.

The catx bat prefers roosting in trees, often selecting dead or dying trees. They use crevices, cavities, and hollows in trees as day roosts where they sleep in groups or colonies during the daytime. They will also utilize artificial roosts like bat boxes. Favorite roosting spots are under loose tree bark or in natural cavities and holes in trees. In winter, they may roost in caves or abandoned mines.

Catx bats exhibit roost switching behavior and do not continuously occupy a single roost. They will switch roosts every 1-3 days on average. This is likely a strategy to avoid buildup of parasites or to seek improved microclimate conditions. Their roost switching allows utilization of a network of suitable roost trees within their home range habitat.


The catx bat is classified as a vulnerable species with an estimated population of only 20,000 in 2023 (source). Their numbers have declined over the past few decades due to habitat loss and human disturbances. Deforestation to create agricultural land and urban development has destroyed much of the catx bat’s natural forest habitat. They are also sensitive to noise and lighting pollution which disrupts their natural behaviors.

Several conservation efforts are underway to protect the remaining catx bat populations. Many national parks and protected areas have been established within their range to preserve forest habitat. Limits on deforestation and urban expansion have also been implemented around known roosting sites. Public education programs aim to raise awareness and reduce human disturbances. Researchers are also working to better understand their habitat needs and identify key areas for protection.

While ongoing conservation efforts have slowed the population decline, the catx bat remains at risk. Further habitat protections, reducing disturbances, and increasing roosting and foraging sites will be key to recovering their numbers. Continued monitoring of wild populations is needed to ensure conservation measures are effective at stabilizing and ideally increasing the catx bat population.

Relationship to Humans

The catx bat’s relationship to humans is complex, involving both conflicts and benefits. One of the main sources of conflict is that catx bats will sometimes roost in attics and buildings, causing damage and nuisance. However, they also provide benefits by eating insects like mosquitoes. There are also some superstitions around catx bats – some believe they are a sign of good luck, while others fear them as harbingers of disease or death. Some also hold the superstition that a catx bat brings extra power when integrated into a baseball bat.

In Pop Culture

The Marucci CATX Smart bat has quickly become a pop culture phenomenon since its release in late 2022. With its sleek, modern design and integrated sensor technology, the CATX bat has captured the imagination of baseball fans and athletes.

The CATX bat has already started appearing in movies, TV shows, video games, and other media focused on baseball and sports tech. For example, the bat made a prominent appearance in the baseball video game “MLB The Show 23,” released in March 2023. Players can unlock the CATX bat as a top-tier item for their created players. This shows the CATX bat’s symbolic association with high performance and cutting-edge tech in baseball culture.

Additionally, the bat’s integrated sensor, which can measure swing mechanics and ball impact metrics, is symbolic of the data-driven revolution occurring in sports. Using the latest tech to optimize performance reflects cultural values around innovation, competitiveness, and human augmentation. As more real and fictional athletes adopt smart bats like the CATX, it solidifies the technology as a cultural touchstone representing the future of baseball.

Fun Facts

The CATX bat has some unique and interesting traits that make it stand out in the world of baseball bats.

It currently holds the record for the most popular one-piece composite bat among high school and college players, with over 50% market share in 2022 according to Marucci Sports.

An interesting piece of trivia is that the CATX bat is named after Marucci partner and former MLB player Chase Utley’s son “Cat” and his nickname “Cat Daddy.” Marucci combined “Cat” and “X” (for the moniker “X-Man” given to Utley for his extraordinary work ethic) to create the “CATX” moniker.

The CATX bat incorporates Marucci’s AV2 Anti-Vibration knob technology, which aims to reduce negative vibration feedback and provide a smoother swing and feel. AV2 is patented and unique to Marucci bats.[1]

In addition to its one-piece composite construction, the CATX incorporates Marucci’s signature “Ring-Free Barrel” technology, which uses a special carbon-fiber barrel wall design to enhance the bat’s performance and durability while minimizing unwanted vibration.

The 2022 CATX Connect model introduced the first “smart bat” built with sensor technology to connect to an app and provide swing data and feedback for players and coaches. This new innovation sparked excitement in the baseball community.
