It really gets me down that I have to deal with it. My back yard stinks, there are flys everywhere and when the baby gets here, it's bedroom window looks out on this beautiful view!”
don't go near the poo yourself if you are pregnant jeff, runny poo in cats (and dogs) can be a sign of worms- they can be dangerous if you are pregnant.
I am a cat lover and have my own (one on my lap now, another looking jealously down from the windowsill

) but I think ping's cat are feral, which means they are more persistant in using a food source. Ammonia in bleach smells like other cat pee (as another poster pointed out earlier) which only encourages them to pee over the "intruder cat pee" which is how they smell the bleach, to mark their territory. The more bleach you put down, the more they pee.
Ping if you think you will live there for the next few years at least you could try contacting one of the cat charities and enquire about a trap, neuter & release programme. they may be able to relocate the colony (doubtful but it does happen)but if they can't you will at least control the population and feral cats tend to only live for 5/6 years. I know its a lot of hassle for a problem thats not your fault but if you want rid long-term and you'll be doing the cats a favour too which will get you excellent karma and/or rewards in heaven and/or satisfaction if you are a humanitarian atheist
