DNova, not knowing you had posted this question, I had already addressed it here:

To add to it and reiterate what other people have said here -

Cats love to sun themselves in the window. That alone almost guarantees you will be caught. If you are merely dodging a pet fee, most large apartments have too many legal pets for them to notice the ones here and there that are snuck in. But a cat sitting in the window of a no-pets apartment is like a neon sign saying "evict me".

Also, in Texas anyway, landlords can legally come into your unit under certain conditions without your prior permission or knowledge. So even if you have a fool-proof back up plan for everytime your landlord needs access to fix the garbage disposal, change the A/C filter, apply pest control, etc. you are still running a risk if something unexpected happens and your landlord must enter your unit without you knowing in advance.

Again, you live in Florida and things may be different, but Spencer's experience WAS legal and the cats COULD HAVE BEEN REMOVED BY THE MANAGER and he could have been evicted with only three days notice, even if he agreed to remove the cat(s). You might want to read your lease and/or consult with an attorney or visit the legal section of your library to find out exactly what can happen in Florida.

Please take everyone's advice and find a place that will welcome your kitty. I have been very lucky through the years and have often been able to find a place that charges no extra fees. But, of course, to do that you have to be willing to stay away from those "complexes" run by those management companies - in Texas they are nothing but legal highway robberymen - they'll fee and fine the food right off your table, even after you leave, like Spencer pointed out. (You must understand that it probably cost them about $100 to replace that carpet - they use cheap material and their own labor - most of the time they don't even replace it - they just clean it and dye it and still charge you for replacing it) Can you tell I used to manage apartments a long, long time ago?
