We also use World's Best Cat Litter, I believe it's made of corn... one great use for it! My cat is 18 years old and has kidney disease, and this is the only litter that can take all the abuse (way more volume than before he was sick).
Both our cat & dog eat grain free for the most part, although we are not super strict - especially with the dog.
Have to agree with you, OutdoorAmy, on the poop picking-up. I see why you would do it in some areas, like my previous home in a very manicured neighborhood... there were fines for leaving dog poo and yes people would report you. Always annoyed me, but I understand that the "image" is very important. Luckily where I live now out in the country, it is very dog-friendly. People let their dogs go wherever, and you are more likely to step on deer poo than dog poo anyway. If I were in a town, I'd pick up if it were in someone else's yard or a kid's playground, etc. But things here are more "natural" and most people seem to consider poo=fertilizer.
