Please Help Me Pay My Deposit! Sleeping in my car

Hi, everyone. My current landlord completely screwed me and gave me a 48-hour notice to leave. I was in a car accident and was late on my rent this month. Technically, what he is doing is legal and I'm completely screwed. I have been sleeping in my car for the last two days and had to give up my beloved cat, Minnie of 11 years which devastated me. I received a housing off today but I have to pay the deposit by tomorrow! Please help me get out of my car, into an apartment, and get my cat back! I've never been in a worse situation and I'm exhausted. Any help will do. Please help! :(
