Minimum desex ages selected for male cats, and female cats, by veterinarians with different career lengths. Four vets selected no minimum desex age for male or female cats and were excluded from log-linear analysis (question answered by 93% of 61 vets). Two desex age categories were pooled because of small sample sizes (≤1 and 1–2 months). Six career length categories were pooled into three because of small sample sizes (<1 and 1–5 years vs. 6–10 and 11–15 years vs. 16–20 and ≥21 years). There were no significant three-way interactions between career length, desex age, and cat sex (G2 = 10.22, d.f. = 22, p = 0.98).
