There were no statistically significant differences among the groups with respect to age, weight and sex ratio. Each group consisted of various cat breeds. Serum SOD activity was significantly lower in the HCM group (mean 0.99±0.35 U/mL) and A‐HCM group (mean 1.39±0.4 U/mL) compared to the healthy controls (mean 2.07±0.76 U/mL, p<0.01). Serum CAT activity was significantly lower in the A‐HCM group (mean 19.4±4.2 nmol/min/mL) compared to the HCM group (mean 23.6±5.9 nmol/min/mL) and healthy controls (mean 30±7.5 nmol/min/mL, p<0.01). There were no significant differences in the serum activity of GPx (p=0.21) or plasma TAC (p=0.89) between the groups. Serum SOD activity correlated with the CAT activity (r=0.44, p<0.05).
