This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
狳 combines the animal radical 犭 with 余, which likely contributes a phonetic element. The exact historical development is uncertain.
With no clear meaning, picture a mysterious animal (犭) whose name sounds like 余 (ヨ), but its true nature remains unknown.
For ヨ, imagine a yo-yo tied to the animal radical: yo -> ヨ, and the animal plays with it.
