I saw the movie Isle of Dogs (2018) yesterday. The narrative described a kingdom of cat-loving humans waging war against the dog kingdom.1 Later, some characters spoke only Japanese without subtitles or interpreters. Since I understand some Japanese, I got some Bilingual Bonus (warning: tvtropes). In real life, I am not a "cat-person" or a "dog-person", but a "both"-person.
So, all of this got me into world building mode. I started writing a story involving three kingdoms, the cat-lovers, the dog-lovers, and the "both"-lovers. This is where my question comes:
What's the word to describe a person who loves two entities?
I would like to form a sentence like below:
The cat-loving kingdom and the dog-loving kingdom have been at war for centuries, with the bi<what?> kingdom acting as the peacemaker to prevent a catastrophe.
so that it reads similar to:
The English kingdom and the French kingdom have been at war for centuries, with the bilingual kingdom acting as the peacemaker to prevent a catastrophe.
Obviously, I don't want to go with "bi-lover" (or similar) due to certain connotations.
1 It is from one of the earliest scenes and not particularly relevant to the plot, so not a spoiler.
