So I live in an apartment in pasadena,tx for the past week the stay cats we have around her have been pooping all over my patio witch I hate because me and my son can't play out there. I have called the office three days in a roll and they still have not done anything about it. Who should I call for my apartment to finally do something about it. And what can I do to stop them from coming on to my patio I have a 2 year old and I don't want to kill them so is there something I can put out there to scare them off that won't hurt them

There is stuff you can buy at a pet store that deters dogs and cats from the area. It's a spray, I'm sorry I can't remember what it's called, but it has always worked for me.
The pet store will be able to get you to the one that works the best.

Are you talking about the neighbours cats? You can not let your cat out for a while, and the other cats won't come finding him and eventually stop. I know its mean but that's a method.
