Provided are a weight scale, a weight measurement method, and an animal toilet that can easily achieve high-precision weight measurement while using an amplifier and an A/D converter that are not high-precision or high-resolution. The weight scale comprises a load cell, an AMP, and an ADC. In a preceding weight measurement of a measurement subject, the AMP is set (S3) to a first measurement rangeand a first amplification factor, an output voltage of the load cell is amplified with the AMP, the output of the AMP is subjected to A/D conversion by the ADC, and a first weight value of the measurement subject is calculated (S4). Provided is a CPU that, in a following weight measurement of the measurement subject, sets (S5) the AMP to a second measurement range that is narrower than the first measurement range and a second amplification factor that is greater than the first amplification factor, then amplifies the output voltage of the load cell with the AMP, subjects the output of the AMPto A/D conversion by the A
