When both dogs and cats were grouped by age, a clear trend was observed indicating that mammary tumors were more frequent in older cats (χ 2 (4) = 35.43, p = 3.8 × 10 −7 ; Cramér’s V = 0.224; OR/RR + 95% CI).

The oldest cats (≥12 years) were more frequently affected than dogs, although this difference did not reach statistical significance.
