"Roommate thinks my cat is 'our' cat": Fed Up Cat Owner Tries to Find Peaceful Ways to Navigate A Frustrating Feline Conflict

Those of us who have at some point in our lives lived with roommates know that having roommates can be a total disaster. Speaking from my own experience, moving to a big city and needing to find an apartment ASAP causes you to compromise on some things, but roommates shouldn't be one of them. Unfortunately, that's often the way the cookie crumbles. From messy roommates to roommates who use the kitchen to cook the weirdest and most unappealing foods, to roommates who never take their clothes out of the dryer, there often is much to be desired. 

For the original poster of the thread we are featuring today, a frustrating feline situation left them feeling confused and fed up as to how to approach their roommate. The roommate in question completely crossed the line when it came to OP's cat, often referring to the cat as their shared cat, rather than OP's cat. The kicker is that this cat is OP's childhood cat and of course, OP covers all of the cat's expenses. What would you do in a situation like this? We would have to move out at all costs.
