Laura is right; you're already maxed out. If you've exceeded the city limit, you could face a real problem should someone decide to report you. One of the PTers got evicted from her apt. for just that very situation and is having to rehome some of her cats. I'd hate to see you have to do that. We all have soft hearts and want to rescue every cat that crosses our paths but it just isn't possible. Myself, I was comfortable at 4 but I took it to 8. Financially, it's been tough, especially when I was actively rescuing and had 27 outdoor cats that I was caring for. I don't know your age but I think about my cats outliving me since the average life span of an indoor cat is 17 1/2 years and I'm down to 7 now, the youngest of which is 3. And should one of them need major surgery, I've got to be sure I have the money set aside for it. So, there are lots of things to consider but my philosophy is "people first". Love your cats, help the ones you can and tell the people who try to pawn off their problems onto you that they need to step up to the plate and get busy and get their cats spayed and neutered. Everyone loves a little kitten but then they grow up and become cats and then suddenly no one wants them any more. They need to be responsible. Good luck.
