Laboratory Cat Welfare: Husbandry and Social Needs

Domestic cats used in biomedical research have complex social and environmental needs that are frequently inadequately met in standard laboratory housing conditions.

Key Facts

Cats are used in neurological, nutritional and pharmacological research — the EU uses approximately 3,600 cats annually in laboratory procedures
Cats are solitary hunters but are socially flexible — some individuals are highly social while others prefer minimal conspecific contact
Single housing of cats in laboratory settings causes elevated stress responses and reduced welfare indicators in most individuals
Cats require complex vertical environments with elevated perching, hiding spots, scratching surfaces and novel object exploration opportunities
Studies show cats with positive human socialisation in research facilities are easier to handle, less stressed during procedures and show better welfare indicators
The RSPCA Research Animals Department has published comprehensive guidance for laboratory cat housing that goes significantly beyond minimum legal requirements

Welfare Considerations

Laboratory cats represent a relatively small research population globally but one with complex, well-documented welfare needs that are frequently unmet. Cats in barren cages without vertical space, hiding opportunities or positive human interaction suffer measurable welfare deficits. The irony is that better-welfare cats produce better research data — less stressed animals show fewer stress-related physiological confounds and are easier to handle with less procedural interference. Pair or compatible group housing, structured human socialisation programmes, vertical space, environmental complexity and positive reinforcement training for procedural cooperation all improve both welfare and research quality simultaneously.

What You Can Do

Advocate for pair housing as the default for laboratory cats where compatible individuals can be identified
Support institutional enrichment programmes for laboratory cats including vertical space, hiding opportunities and structured play
Back regulatory requirements for positive human socialisation programmes for all research cats
Encourage institutions to adopt the RSPCA laboratory cat housing guidelines as minimum standards
Support research into alternatives to cat models in neurological and nutritional research
