Anyone have an obnoxious cat, but they love them?

Wow, where to start. I have a female tabby who is reeeeeeally inyourface. She bit my ankle once as I was walking by. Hard. For no reason. She wasn't even mad at me. It just came out of nowhere. She attacks my dachshund but the dachshund thankfully can easily put her in her place. Sometimes I hear a scream (my dog), and I look and the fight is on, but it's over pretty quick. The dog doesn't put up with much crap, lol....I have an older cat, a Maine Coon, a rescue who used to be an all outdoor cat, who could probably take the Tabby, but the older cat is sooo laid back. She pretty much just wants to be left alone. She tries to go in to the potty box, and the Tabby starts a fight. I'm here most of the time as I work from home, so thankfully can supervise 90% of the time, but sometimes I have to go out to meet clients, or once in a while I actually sleep. LAST night I woke up, and the cats are fighting, but I yelled at them, and they broke it up. My older cat has allergies, so when she's due for her meds, or I vacuum, or just so many little triggers, she starts having a sneezing attack, and it appears to irritate the Tabby, and she'll start shadowing the Maine Coon, like she's stalking her, or looking for a fight. I always told myself I would not have a mean animal, but wow, I've had my Tabby for 4 years, since she was a kitten, and I've thought of rehoming her, but she really seems to be attached to me, and follows me everywhere. The other night she sneaked out of the house, and I caught her on the front porch, and she laid down in a submissive pose, and ran back in the house. I know she would love the chance to wander outdoors, but na, not gonna happen. I live in a city, and she's always been an indoor cat, but she always makes that break for the door and freedom. It's like, she's half-feral. I swear she is. She will follow me all day long, even 'guarding' me in the bathroom, and she always plays when I get out her toys, but to hold her? Oh yeah, right. She has this little high pitched scream she does when I pick her up. She hates being held, and she only lets me pet her on her head, and when SHE wants to. Those little idiosyncrasies I can deal with, it's just her personality. But the aggression toward the other cat....not happening. Anyone ever dealt with an obnoxious cat, but you still loved them? Good tips so appreciated!!
