I would not know what to do, besides honestly talk to them and express your concerns. =( Poor kitties, they're put into a position where they are considered a nuisance to so many people, and the owners are putting the cats in danger of being poisoned or hurt intentionally. Not only that, but they are so at risk of being hit by cars while roaming around night & day. I HOPE they are all altered!

Sorry, but IMHO, why do these people even want to keep cats if they are outside 24/7? It makes as much sense, to me, as keeping a dog in the backyard it's entire life and giving it 5 minutes of attention. I *hate* the "Well, cats are meant to be outdoors, blah blah" excuse. Seriously. Lola gets to romp in the backyard while we're out there watching her for at least a few hours a day... that does not mean I'm going to give her free roam of everyone elses property. I cannot imagine how horrible I would feel, as well, if a neighbors cat came into my yard and was hurt or killed by my dogs (although neither of my dogs would ever do this - just imagining if I had a dog with high prey drive). It's totally a double-standard that (rightly) dogs are generally not allowed to roam, but cats can go anywhere & everywhere. They do cause a nuisance, especially to people who are not into animals... we had to get a sealed cover for our sandbox for this very reason, it's very gross to find cat droppings everywhere, while I on the other hand dutifully pick up after my dogs if they potty on walks
