I am in California and we have a shelter in place order in effect. We are able to go outside freely. We can take out the trash, go to the grocery store, get gas, etc. Public playgrounds are closed but people can still walk around a park or around their neighborhood. They are asking people to still avoid each other if walking outside but they aren't saying it's a lockdown in your house thing.Illinois is about to announce in shelter in place. I don't know much about that but does that mean my feral cats in my back yard won't be able to eat if Missouri does this? I would hope we could go into our yards at least to dispose of garbage or we'll have a 2nd problem on our hands.
It's more all the non-essential business are closed and don't go out if you don't have to.
