Maine Coon kittens & cats in Colonial Heights, Virginia

I feel that this cat has potential for adoption because she has basically "adopted me". She waits for my truck each day until I get there to feed her and has hops in the truck with me to get warm during this so far unforgiving winter. I put a small pet house behind the bushes where she stays most of the time, but she likes to roam the parking lot and I'm afraid that one day some crazy tenant driving like a maniac might hit her. Once fed, she becomes very affectionate. I cannot take her inside my apartment because the rental company here charges an outrageous initial fee for pets and $35 a month every month thereafter. I'm much older, retired and on a fixed income and I simply cannot afford her food, litter, medical care or the monthly fees. I'm at my wits end as far as what to do with this situation and I hate that she has to endure this freezing weather. I seriously need help with this problem.
