Reliable Monitoring of Shelter Cat Well-Being Using Ordinal Rating Scales [Abstract]

Abstract

Introduction

Monitoring psychological well-being is a core component of effective feline shelter medicine and population management. Shelters routinely implement enrichment, housing modifications, and behavior-focused interventions intended to reduce fear, anxiety, and stress and to promote adaptive behavior¹. However, objective and standardized methods for tracking behavioral change over time remain limited in many facilities. Assessments are often based on informal descriptors or subjective impressions that vary among caregivers, shifts, and professional backgrounds, reducing consistency and limiting the clinical utility of behavioral observations.

Cats pose particular challenges for welfare assessment due to their subtle behavioral expression, especially in confined or unfamiliar environments. Behavioral indicators of compromised well-being may be overlooked, misinterpreted, or inconsistently documented, while gradual improvements may go unrecognized. From a clinical perspective, this limits the ability to evaluate intervention efficacy, prioritize cases, and make evidence-informed decisions regarding treatment, housing, or outcome planning.

Ordinal rating scales offer a practical solution for applied settings by providing structured, repeatable measures of observable behavior². Rather than categorizing cats as simply “doing better” or “having a good day,” ordinal scales allow caregivers to report specific behavioral indicators across a continuum, facilitating assessment of the success or failure of targeted interventions. The aim of this study was to validate four ordinal rating scales designed to monitor psychological well-being in shelter cats and to determine whether high interobserver agreement and reliability could be achieved following structured training, as previously described in the primary research publication³.

METHODS

Scale Development

Four ordinal rating scales were developed to measure specific behavioral indicators relevant to feline psychological well-being in shelter environments: a modified Fear, Anxiety, and Stress (FAS) scale⁴, a Response to Petting (RTP) scale, a Participation in Play (PIP) scale, and a Food Intake Summary (FIS) scale. Each scale was scored from 0 (best) to 5 (worst), with each numerical value anchored to explicit, observable behavioral criteria. Descriptors were written using explicit, behaviorally anchored criteria to reduce subjectivity and reliance on personal interpretation, consistent with recommendations for observer rating tools².

The modified FAS scale summarized overall behavioral presentation, including body posture, muscle tension, and avoidance or engagement. The RTP scale assessed behavioral responses to gentle human contact, reflecting enjoyment of handling. The PIP scale evaluated engagement with play opportunities, which may reflect affective state. The FIS scale summarized food intake patterns, recognizing the close association between appetite, stress, and health in shelter cats⁵.

Participants and Training

Sixteen shelter staff members and volunteers from a large urban shelter participated in the study. Participants completed a four-hour structured training program covering all scales. Training included review of scale intent and definitions, discussion of common scoring challenges, and guided practice using videos and photographs. This approach was designed to promote consistent interpretation of scale descriptors across observers.

Reliability Testing and Analysis

Following training, participants independently scored 30 standardized visual examples (videos or photographs) per scale. Interobserver agreement was evaluated using linear weighted kappa (κ) statistics, and reliability was assessed using intraclass correlation coefficients (ICC). These metrics were selected to quantify both agreement and consistency among multiple observers rating ordinal data⁶. No animals were directly used for the purposes of this study; all ratings were based on existing operational video data.

RESULTS

All four ordinal rating scales demonstrated strong performance following structured training. Average interobserver agreement for each scale was classified as “almost perfect,” with κ values greater than 0.80 for all scales. Reliability was also excellent, with ICC values of 0.90 or higher across all four measures. These findings indicate that observers with varied professional roles were able to apply the scales consistently after a relatively brief training period.

In addition to quantitative reliability outcomes, applied case examples illustrated the clinical utility of the scales for tracking behavioral change over time. Longitudinal scoring allowed detection of both gradual improvements and emerging declines in behavioral indicators, supporting timely and targeted intervention. These case applications demonstrated how ordinal scores can complement clinical assessment by providing objective behavioral trends rather than isolated observations.

DISCUSSION

The results of this study support the use of ordinal behavioral rating scales as reliable tools for monitoring psychological well-being in shelter cats when paired with structured training. High interobserver agreement and reliability are critical prerequisites for the clinical utility of any behavioral assessment tool², particularly in shelter environments where multiple caregivers contribute to welfare monitoring.

From a shelter medicine perspective, the ability to track behavioral trends over time within individual cats is especially valuable. Baseline behavior varies widely among cats, and meaningful welfare changes are often incremental rather than dramatic. Ordinal scales allow clinicians and caregivers to detect these changes, evaluate responses to enrichment, housing modification, pharmacologic support, or behavior intervention, and adjust care plans accordingly.

The structured instructional approach used in this study was likely a key factor in achieving high agreement and reliability. Importantly, these tools are not intended to replace comprehensive veterinary or behavioral assessment but to serve as standardized adjuncts that improve communication and documentation. The availability of asynchronous training for three of the four scales further enhances feasibility and supports broader implementation in shelter and clinical settings: https://torontohumanesocietycourses.thinkific.com/courses/Feline-Behavioural-Ordinal-Rating-Scales.

CONCLUSION

The four ordinal rating scales evaluated in this study provide reliable and practical tools for monitoring psychological well-being in shelter cats. When supported by structured training, these scales enable consistent behavioral assessment across observers, facilitate longitudinal monitoring, and improve the evaluation of welfare-focused interventions. Incorporation of standardized ordinal behavioral assessment into routine shelter medicine practice has the potential to enhance clinical decision-making, case management, and overall feline welfare.
