I did just notice some more things about Dobutsu Shogi (I was trying to write it from scratch myself, since I'm still learning the Ludii Language):
These are the rules documents I'm aware of for the game:
Dōbutsu shōgi - Wikipedia (English rules on that page, Japanese rules under "External Links")
Let's Catch the Lion! | English rule | File | BoardGameGeek (Japon Brand)
Let's Catch the Lion! | Let's Catch the Lion Rules in English | File | BoardGameGeek (nestorgames)
The nestorgames rules mention:
"You cannot place your lion on your opponents last square if it would put you in check."
This is not implemented, however does not seem to come up in the Japanese rules linked above (at least not on Google Translate, you'd probably need an actual translation). Adding this via the (option) ludeme could be an idea.
"If a game position is repeated 3 times the game ends in a draw."
This is not implemented and does come up in the Google Translated Japanese rules.
