Figure 1 Core temperature changes from control after castration with significant changes (*P < 0.05, **P < 0.01, ***P < 0.001). CI = confidence interval.

Figure 2 Changes in pain score (CMPS-SF: Reid et al., 2007) over 12 observations after castration. CI = confidence interval; CMPS-SF = Short-Form Glasgow Composite Measure Pain Scale.

Figure 3 A possible relationship between “extraversion” and peak temperature increase after castration. However, this is not statistically significant (Spearman: rs = 0.438, n = 15, P = 0.101).

Figure 4 The relationship between extraversion and peak discrepancy (PD) in eye temperature (Pearson: rs= 0.546, n = 14, p = 0.035). Positive PD scores indicate the right eye temperature is higher, and negative scores indicate the left eye temperature is higher.
