Cat Sitter Entered My Home After Being Told She Was No Longer Welcome (il)

Location: Wilmette, Illinois

We hired a cat sitter through Rover. She showed up late and then left our cats alone for ~24 hours. She was not responsive to messages. She came back then disappeared again and missed the cats breakfast. I told her she was not to return and we found alternative arrangements. She could collect her things when I returned later this month. She didn’t respond for many hours. I sent a friend to check on our cats and found them without food and that she had brought and left her (unauthorized) cat in our bedroom who also didn’t have food or a litter box beyond a pee pad. The cat obviously had an upper respiratory infection that she has now exposed my cats to. She was able to take a picture of something with the sitters full name and contact information since I don’t have that through Rover. There were also multiple vomit and hairballs from the cats. My cats rarely do either so this is unusual. All cats were fed and cared for before my friend left.

Cat sitter responded, never admitted anything about the cat, and basically just said she had been there the whole time. I have camera footage and a door log that says otherwise. I reiterated she was not to enter my home. My husband decided to leave our trip and fly back home as quickly as possible which would take about 24 hours. It was just feeling too unsafe and chaotic. She messages again and says she needs to get her stuff and invites me to have a “trusted friend” there when she does so. She entered my home 2 minutes after I received that message. She took her cat and all but one of her 8-10 bags of clothings and other items. I have a log of everything and I am working on a refund through Rover but they won’t cover the flight and or cleaning the house. I assume this isn’t worth pursuing to try and get the cost of the flight from her, but I don’t know if I’m missing anything legally. We are changing the locks and door codes. I feel like my home was violated.

My questions are this:

1. how long do I need to hang on to the bag of clothes she left before they are considered abandoned?
2. 1a) if she does contact me for her clothing, can I leave it at a police station?
3. is this a restraining order situation?
