Zoo Med Laboratories, Inc., commonly known as Zoo Med, is an American company that specialises in products for reptiles, amphibians, fish, birds, insects, and other exotic pets. Founded in 1977 by reptile enthusiast Gary Bagnall, the brand is widely recognised as a pioneer in modern reptile husbandry, particularly for its lighting systems, habitat equipment, nutritional supplements, and environmental care solutions.[1]

Headquartered in San Luis Obispo, California, Zoo Med develops and manufactures a comprehensive range of specialty pet care products used by hobbyists, breeders, zoological institutions, and animal care professionals globally.

Early beginnings (1970s–1980s)

The origins of Zoo Med lie in founder Gary Bagnall’s early passion for reptiles and wildlife. As a teenager, Bagnall became deeply involved in keeping, breeding, and trading reptiles. Before establishing Zoo Med, he operated a reptile import and export business which eventually evolved into a larger animal supply operation.[1]

In its formative years, the company focused heavily on reptile-related products at a time when reptile keeping was still developing as a serious hobby. Many species were difficult to maintain in captivity due to limited understanding of their specific nutritional, heating, and lighting requirements.

In 1984, Zoo Med introduced ReptiVite, one of the earliest vitamin and mineral supplements formulated specifically for reptiles. This product helped establish the company as a specialist in reptile nutrition and husbandry.[1]

One of Zoo Med’s most significant contributions to the field of herpetoculture was the development of specialised UVB lighting for reptiles.

In 1993, the company introduced the ReptiSun UVB lamp, the first commercially available UVB fluorescent lamp designed specifically for reptile use. This innovation transformed captive reptile care by enabling keepers to provide the ultraviolet radiation necessary for natural behaviours and vitamin D3 synthesis.[1][2]

Prior to the availability of specialised reptile UVB lamps, many captive animals suffered from improper lighting conditions that contributed to health issues such as metabolic bone disease. Zoo Med’s UVB products significantly influenced housing standards for reptiles in private homes, zoos, and breeding facilities.[2]

Zoo Med produces a diverse array of products across several animal care categories.

Reptile Lighting

Lighting remains one of Zoo Med’s most prominent product areas. Major product lines include:

• ReptiSun® UVB lamps
• T5 and T8 fluorescent UVB systems
• Compact fluorescent UVB lamps
• Mercury vapour lamps
• LED reptile lighting systems
• Lighting fixtures and accessories

These products are engineered to provide varying combinations of ultraviolet and visible light to meet the specific environmental needs of different reptile species.[2]

Heating Equipment

The company manufactures heating products intended to recreate natural temperature gradients within reptile habitats. Examples include:

• Ceramic heat emitters
• Heat lamps
• Under-tank heaters
• Thermostatic accessories
• Heating fixtures

Proper heating is a critical component of reptile husbandry, as many species rely on external heat sources to regulate their body temperature.

Terrariums and Habitats

Zoo Med produces complete habitat systems and enclosure accessories, emphasising environments that imitate natural ecosystems.[2] Products include:

• Glass terrariums
• Naturalistic terrarium systems
• Screen cages
• Reptile habitat kits
• Substrates
• Hides
• Climbing structures
• Water dishes
• Décor items

Nutrition and Supplements

Zoo Med offers food and nutritional products for various exotic pets, including:

• Reptile vitamin supplements
• Calcium supplements
• Turtle foods
• Aquatic animal foods
• Insect-based feeding products

The ReptiVite line remains one of the company’s historically significant products in this category.[3]

Aquatic, Bird, and Other Exotic Animal Products

Although best known for reptile care, Zoo Med also manufactures products for:

• Freshwater aquarium animals
• Turtles and aquatic reptiles
• Birds
• Small exotic pets
• Invertebrates

Zoo Med’s corporate identity is closely tied to the reptile-keeping community. The company describes itself as being founded by animal hobbyists and focuses on developing products based on the biological needs of captive exotic animals.[4]

The company also operates educational resources such as Zoo Med University, which provides training materials covering reptile care topics including habitat setup, lighting, heating, humidity management, and nutrition.[4]

Zoo Med states that many of its products are developed and tested through practical animal care experience. The company maintains collections of reptiles, amphibians, fish, and other exotic animals used for product evaluation and husbandry research.[5]

A significant portion of the product line is manufactured at the company’s California headquarters, where production facilities support its goal of creating specialised equipment for exotic animal care.[2]

Zoo Med is considered one of the most recognisable reptile care brands worldwide. It is particularly respected for:

• Its long history in reptile husbandry
• Early development of reptile UVB lighting
• Wide availability in pet stores
• Educational resources for keepers
• A large product ecosystem covering complete habitats

Many reptile keepers regard Zoo Med products as suitable for beginners while also offering advanced equipment utilised by experienced hobbyists.

Like many companies involved in captive animal care, Zoo Med has faced criticism from certain animal welfare organisations regarding reptile enclosure recommendations and captive keeping practices. In 2020, People for the Ethical Treatment of Animals (PETA) filed a lawsuit involving claims about reptile enclosure practices. Zoo Med and members of the reptile-keeping community have disputed such criticisms, emphasising a commitment to improving captive animal care through research and education.[1]

Zoo Med’s primary contribution to the industry has been the professionalisation of reptile keeping. The company helped shift reptile care from basic containment towards a more science-based approach involving:

• Correct ultraviolet lighting
• Temperature management
• Species-appropriate habitats
• Specialised nutrition
• Environmental enrichment

Its innovations in UVB lighting, in particular, played a major role in making long-term captive reptile care more successful.[2]

Zoo Med Laboratories is among the most influential reptile care companies globally. Originating from a reptile hobbyist background, the company grew into a major manufacturer of exotic pet products. Its most enduring legacy is the advancement of reptile lighting technology, especially UVB systems, while its broader product range now encompasses nearly every aspect of reptile and exotic animal husbandry.[2]

Today, Zoo Med remains a prominent brand among reptile keepers, breeders, and exotic animal enthusiasts, recognised for combining product innovation with education and animal care knowledge.[4]
