Comprehensive Guide to Laboratory Animal Caging Systems and Housing, Animal Cages Types and Space Requirements in Laboratory Settings

What are microusolation cages used for?

They are used for housing animals in a controlled environment to prevent contamination.

What happens if ventilation fails in animal cages?

CO₂ levels can rise inside the cages, which can be harmful to the animals.

What do digital ventilated cages (DVC) track?

They track bedding moisture, food and water levels, and leaks.

What are biocontainment cages designed for?

They are specialized microisolation cages for housing animals in infectious disease studies.

What is a key feature of biocontainment cages?

They have airtight seals and cage clamps to prevent accidental opening.

What regulatory bodies oversee biocontainment cages?

The CDC (Centers for Disease Control and Prevention) and USDA (United States Department of Agriculture).

When are disposable cages used?

They are used when there are limited cage washing facilities or for studies involving radioactive materials.

What is the purpose of suspended cage systems?

They are used for larger rodents and allow for easier cleaning and maintenance.

What type of flooring is commonly used in large animal caging?

Wire mesh floors, solid bottoms for cats, and plastic floors for guinea pigs.

What is the difference between modular stacked cages and suspended cages?

Modular stacked cages are fixed in place, while suspended cages allow for easier access and cleaning.

What are group caging systems?

They are designed to house multiple animals of the same species in mobile or stationary cages.

What materials are commonly used for flooring in runs, pens, and kennels?

Vinyl, mesh, slotted coated steel, or fiberglass.

What are squeeze cages used for?

They allow for safe handling of non-human primates by sliding the back wall forward.

What is the purpose of aquatic caging systems?

They are designed to house aquatic animals like frogs and zebrafish, requiring a continuous flow of water.

What are cubicles in animal housing?

Mini animal rooms within a larger space that can maintain different temperature, lighting, and humidity levels.

What types of animals are typically housed in agricultural housing?

Swine, sheep, goats, and cattle, often kept in indoor pens or pastures.

What is a key requirement for aquatic caging?

There must be a continuous flow of water going in and out.

What is the function of enrichment in animal housing?

To provide stimulation and improve the welfare of housed animals.

What features are important in housing non-human primates?

Cages must have perches, enrichment activities, and allow for outdoor play.

What are specific use cages designed for?

Specific use cages are designed to accommodate separate tubes and monitor parameters such as feces output.

What parameters can metabolism cages monitor?

Metabolism cages can monitor food and water intake, as well as collect data on CO2 and oxygen intake levels.

What is the purpose of transport and transfer cages?

Transport and transfer cages, also known as 'jump boxes', are used to move animals to a facility or within another facility.

What is a key requirement for animal cages regarding space?

Cages must provide enough space for animals to express their natural posture.
