Highlights • Anti-Leptospira IgG seroprevalence was estimated on cats from Lisbon, Portugal via ELISA.• A mathematical model was applied to raw data to establish the real cut-off value of seroprevalence.• Of the 243 samples, 59.3% tested positive for anti-Leptospira IgG.• A positive correlation between low anti-Leptospira IgG and FIV+ was detected (p = 0.02).• No correlation was detected between anti-Leptospira IgG values and outdoor lifestyle.
