Unless you actually know and understand what and who the furry community actually is perhaps it's best not to just assume. Understanding a lifestyle, age demographic, race, etc. is essential to knowing who your target audience is.
Ex. I can't expect everyone to like my comics as it is based around college and work life. Children aren't going to care for strips about paying bills and annoying customers because they don't understand those things, and people over 40+ won't care because they've either already been through it or don't care anymore. To pertain more to your question at hand: I wouldn't tag it as "Military". Yes, military do go to college and do work, but it isn't specifically about them, so I wouldn't tag them as a main audience because their military, instead they're just a demographic based on age.
How much do you know about furry culture to really say "you guys, like this, it has animal people in it." I'm not saying you need to infiltrate a convention, but instead of viewing them as just a tag, maybe some research and understanding could help give yourself some perspective. No one on here would consider Gamercat as "furry" and they'd be right because it isn't specifically made for furries but rather anyone who generally likes gaming, and if they happen to be a furry "hey way to go."
