My dogs poop outside and periodically DH goes out and rakes it up. It gets bagged and put in the trash bin out by the curb. They don't poop on walks so I don't have any strategies for handling it other than that, really.
And my dogs have always, always, always been into the cat box. All three of them. Really the only thing I have been able to do about it is keep it in a gated area so they can't get to it. Gwennie knows it's bad but apparently it's worth it. I wish you luck training Molly out of that one. If you manage to, I'd love to know what worked.
I'm a big believer in gates, though. I have the kitchen area gated off, and the entire bedroom/bathroom section of the house is also gated off. Until puppy learns to listen more it's easier to prevent than discipline afterwards.
