My cat Niggy was given to my by my ex roommate Lisa, her cat had a litter and he was part of it. We paid to have him fixed but I was in the hospital in pre-term labor and my fiancee was at work so her name is on his paper. Our cat Maggie was adopted by another ex roommate of ours, Adam, from a shelter. He moved out one day without warning and left her at our apartment. We have not seen or heard from him since. I have her medical records and her adoption papers, which are in Adams name. I'm just curious who owns them because I pay for everything for them, food, shots, litter, water, everything.
