I don't currently have any racoons in my neighborhood but there used to be some HUGE ones running around. Mind you I lived in San Francisco! It was a residential area without many gardens but they must have lived in Golden Gate Park though it was at least ten blocks from my house.
My warning is that while they are very cute, my friend had bunnies who lived in bunny hutches outside. One day he came out to find his poor fluffs had been mauled and killed. He lived in Oakland which is also pretty urban. He said it was definately a racoon. Poor little guys. So if you have outdoor kitties and there are racoons in the hood I'd beware although I suppose kitties can outrun them where the bunnies were trapped.
Another friend moved into a new house only to find in a few days that things in the kitchen were strewn about. She blamed her kitty. Boy was she amazed when she came home one day to find a coon sitting in front of her open fridge. He'd opend a tupperware and was noshing on the salad inside, tossing the olives he didn't care for over his shoulder! Her rather large kitty was on top of the fridge looking down on him quite worried! Seems Rocky came in thru the cat door!
