Provided is a temperature-adjusting apparatus for a pet, with which the comfort level for the pet is enhanced. The present invention provides a temperature-adjusting apparatus for a pet, the apparatus including: a thermal conductor on which a pet sits; a cooling means for cooling the thermal conductor by generating a temperature difference between the thermal conductor and a heat-radiating means; a heating means for heating the thermal conductor; a first temperature-detecting means for detecting the temperature of the thermal conductor; a second temperature-detecting means for detecting the temperature of the heat-radiating means; and a temperature-adjusting means for adjusting the temperature of the thermal conductor by causing the cooling means or the heating means to be operated on the basis of a first temperature acquired from the first temperature-detecting means and a second temperature acquired from the second temperature-detecting means.本發明提供一種使寵物的舒適性提升的寵物用溫度調節裝置等。寵物用溫度調節裝置具有寵物乘坐的熱傳導體、在該熱傳導體與散熱機構之間賦予溫度差而將該熱傳導體冷卻的冷卻機構、加熱該熱傳導體的加熱機構、檢測該熱傳導體的溫度的第一溫度檢測機構、檢測該散熱機構的溫度的第二溫度檢測機構、及基於從該第一溫度檢測機構取得的第一溫度及從該第二溫度檢測機構取得的第二溫度,使該冷卻機構或者該加熱機構動作而調節該熱傳導體的溫度的溫度調節機構。
