Cat Starter Kit (Brookhaven)

Hello, I am looking for a cat litter box & scoop (preferably litter too, just a request). Also some cat shampoo if possible, so we can clean her up a bit. Cat food will be appreciated, preferably wet canned food, however, we are happy to accept what is offered. Anything else helps as well, thank you!

Note: One of our neighbors left a few months ago, and we came to realize that they left one of their cats and no way to contact them. The cat has approached us more regularly recently; we are letting her remain outside for now and I am hoping to get a starter kit to help her out since the weather is getting colder, and it seems as though she has adopted us lol.
