Ugh... what a horrible situation. I was in a similar one for a while in my old apartment. I was only supposed to have 2 animals, and the managers knew I had 2 dogs. Then, some idiot neighbor told them I had 2 cats as well. Well, there was no way in hell I was getting rid of Katie and Joey. It wasn't an option. So I had to make do until I found another place to live when my lease was up. I made sure that they didn't get in the window during the day, and was very cautious whenever I had to transport them anywhere.

As was previously asked, is he going to do a headcount? Does he know exactly how many you have? I'd try exlpaining things to him and if he doesn't see it your way, tell him to go &^%$#@! himself and keep them anyway. What he doesn't know won't hurt him! Is there anyway you can find a new apartment with a landlord who isn't such a *bleep bleep bleep*?

Best of luck! If I lived closer I'm sure my gf would be willing to help you out, but hopefully you won't need anyone's help! Keep us posted!
