它们 + Verb / Verb + 它们
它们 (tāmen) is the third-person plural pronoun meaning "they" or "them" and is used specifically for non-human entities such as animals, objects, or abstract things. It functions the same way as 他们 grammatically but is reserved for non-human referents. For example, 它们很可爱 means "They are very cute" (referring to animals).
