Provided is an absorptive article for pets which can keep an absorptive core from hindering movement of a pet's hind legs. This absorptive article (10) has a lengthwise direction (Y) and a transverse direction (X) orthogonal to the lengthwise direction (Y), and includes a ventral region (11), a dorsal region (12), an intermediary region which is positioned between the ventral region (11) and the dorsal region (12) in the lengthwise direction (Y), and an absorptive body (50) which includes the absorptive core (51). The absorptive body (50) is positioned only to the side of the ventral region (11) with respect to a cut line (48) through which the tail (1) of the pet (2) is inserted, and comprises two absorptive side edges (50c) which are opposite of each other in the transverse direction (X), a first absorbing unit (53) which is opposite of the urination opening of the pet (2), and a second absorbing unit (54) which is opposite of a site away from the urination opening. The absorptive core (51) has a first narrowed portion (separation portion) (61) which separates coupling between the first absorbing unit (53) and the second absorbing unit (54) in the lengthwise direction (Y).L'invention fournit un article absorbant pour animal de compagnie permettant d'éviter qu'un cœur absorbant ne constitue une gêne pour le mouvement des pattes postérieures, lors d'un mouvement des pattes postérieures d'un animal de compagnie. L'article absorbant (10) possède une direction longitudinale (Y) et une direction latérale (X) perpendiculaire à cette dernière, et contient une zone abdominale (11), une zone dorsale (12), une zone intermédiaire (13) positionnée entre la zone abdominale (11) et la zone dorsale (12) dans la direction longitudinale (Y), et un corps absorbant (50) possédant un cœur absorbant (51). Le corps absorbant (50) possède : deux bords latéraux absorbants (50c) qui sont positionnés uniquement côté zone abdominale (11) par rapport à une ligne de découpe (48) dans laquelle
