What can I use to keep raccoons out of my new garden. They keep digging up plants as soon as I plant and replant them?
That sounds like squirrel behavior. They love newly dug dirt for tucking away winter provisions. If it is a raccoon, there isn't much short of trapping it or using an electric fence. Since they can dig and climb and have amazing hand dexterity, typical fencing techniques are ineffective. If you have a water feature, they will like you! Make sure bird feeders are inaccessible; raccoons like nuts and some seeds. You might rig up a motion-activated light or sound system to scare them away. Of course, this will drive your insomniac neighbors bonkers. I wonder if putting a row cover over the top will deter them. Unfortunately, I don't know if they hunt veggies more by sight or smell. Good luck.
How long do I have to wait to plant food crop in box that my cat used for litter box?
I would remove the litter, and and spray the area with neem oil, and rosemary oil, with a few drops of coconut oil in water. Although the soil itself isn't toxic, the cats can carry parasites that can infect your plants, and therefore you. As long as you treat the area as I mentioned, then you will be free to plant any time.
