<human>: So I basically helped raise this cat with a friend and I get to see him very regularly but the other parent is leaving the country soon and needs someone to look after the little guy. Naturally I was first in line but my roommate is allergic to cats (when he visits our other friend with a cat, he says he has trouble breathing). I love this little guy and being a depressive with anxiety problems, having a pet could really help me out but the roommate is unwavering. Has anyone here developed a tolerance? How long did it take/how bad were your allergies? 

My argument is that it's my apartment too and the least we could do is see how it goes for a week or 2 (with closing my vents, combing his hair regularly, keeping him in my room, etc) because when I'm not home, he likes to go outside anyway. Thoughts? Suggestions? As you can see, this is very important to me. He's like my son!

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Roommate allergic to cats. Won't let me get a 80% outdoor cat even if vents closed, stays in one room, etc. Tolerance development? How long?
