It's a bit complicated

With no further qualification, dogs. I've had dogs for most of my life and home just doesn't feel homey without a dog to me.

But my wife and I have a bit of a thing for frogs, they're sort of our unofficial mascot.

I also thought narwhals were cool long before reddit had them baconing at midnight. I think they were kind of when I realized that kids can be smarter than/know things that grownups don't. I don't remember what exactly the context was, but I remember once bringing them up, my mom didn't believe they were real, so I marched my way upstairs to grab the book I read about them in to show her.

I also always liked Coatimundis (Coatis) because they were probably the weirdest animal the fairly small zoo I grew up near had.

And if I had to pick sort of a "spirit animal" for myself, it's probably a raccoon.
