Kyota Ko did this video as an explainer. They tried to eradicate more confusing and irregular Kanji readings because they often make no sense and you don't deal with all animals every day. So just write them in katakana and that makes it obvious enough you're dealing with an animal and you don't need subtitles for it.
The animals that regularly get a Kanji today are common AND their Kanji has - in the logic of Japanese - unambiguous readings (e.g. 猫, 犬, 像, etc.).
Don't ever encourage Japanese to do more with Kanji. Won't anybody think of the gaijin?
