An absorbent sheet for pets that is highly effective in concealing pet excrement. The absorbent sheet includes: a liquid-permeable front-surface sheet; a liquid-impermeable back-surface sheet; an absorbent body that is provided between the front-surface sheet and the back-surface sheet, and that absorbs liquid that has permeated through the front-surface sheet; an intermediate sheet that is arranged between the front-surface sheet and the absorbent body; and a color arrangement region that forms a color arrangement pattern together with at least one of the front-surface sheet, the back-surface sheet, and the absorbent body. The front-surface sheet is formed so as to have a lower total light transmittance than the intermediate sheet.
