豺

Left beast radical 豸 — Kangxi #153, a side-view of a long-bodied predator: head, arched spine, four legs, drooping tail. The indexing radical, marking 豺 as a wild canid. Same radical groups 豺 with 豹 (leopard), 貂 (sable), 貉 (raccoon dog) — felines and lupine creatures. Distinct from 犭 which covers dog-like mammals more broadly.

Right 才 supplies the sound — cái shifting to chái through a regular c/ch alternation. 才 itself originally depicted a sprouting plant pushing through soil. Same phonetic feeds 材 (timber), 财 (wealth), 在 (at), all in the cái family. Choice of 才 here is purely phonetic; the canid lives in the radical.
