The only reason I am keeping her in a flat where pets aren't allowed is because if I didn't take her in she'd more than likely just have been set free by her owner and be dead by now.

Now I'm attached to her, and she's attached to me. I'm not going to get rid of her just because the management of the place (I live in a housing project for 16-25 year olds who have nowhere else to live, nobody 'chose' to live here) say they're not allowed. Nobody's going to become ill when the cat is staying in my flat only. Walking through the corridor past my front door is highly unlikely to cause an allergic reaction.

Basically, I did what I had to do for my cat at the time, and I don't think either of us would be happy if I sent her away, so that's really not an option. And I'm not asking her to stop acting like a cat, getting your cat spayed is forcing her to stop acting like a cat, and hundreds of thousands of cats are spayed every year (of which only a tiny percentage encounter complications during or after the precedure)

Ok, rant over
