I decided to shoot my shot by Googling "shooter game with anthropomorphic characters" and first result is Small Arms https://en.m.wikipedia.org/wiki/Small_Arms_(video_game)#:~:text=Small%20Arms%20is%20a%20hybrid,deformed%20people%2C%20with%20ranged%20weapons
. It's a platformer as well and the protagonist may fit your description, but it's not purely single-player like you described; there's a multiplayer mode.
I'm afraid that's not it. It was a browser game, and it was 2D.

Is it Jazz Jackrabbit? It is not exactly identical to your description but it is the first game that came to mind before you described the characters.
Afraid not. It's not quite that old, think more late 2000s web games.

Was this a VG Cats fangame?
I have no idea. It might not be, since the girl was more ditzy than the boy.

I'm pretty sure none of these are what you're looking for, but I'm still going to throw out some wild guesses just in case they help.
Twin Shot by Nitrome?
They're not what I'm looking for, but they are similar to what I'm looking for.

Make a newgrounds account and ask on the forums there. They know more about flash games obviously, and newgrounds these days is a lot more helpful than 20 years ago.
Thanks for the suggestion, I'll try that.

UPDATE: After almost a year of being bothered by this missing game, I finally found it! The game is called Scratch the Bounty Hunter, and it was made by Joey Betz, who also made famous flash games like Crush the Castle.

This game has been driving me crazy for at least a week. I found it around 2010 and it was one of those platformer-shooter games, like Armor Mayhem or Raze, but it was purely singleplayer and the two main characters were furries. It had a lot of comedic fourth wall breaking moments, like one character telling the other character the controls and neither of them knowing what they mean. The character you played was a male grey cat I think, and I think the second character was a female with red hair, and the second character would talk to the player character through a computer and give advice and maybe hack things?
