My friend desperately needs hospice help, but he refuses to consider the option. Who or how can I contact someone to help him?

My friend has stage 4 cancer and is in total denial about his situation. I have tried repeatedly to talk to him about hospice care and he says he doesn't need it.He has animals he cannot care for and refuses to let them go to a better situation, but calls me to care for them and cries when I try to talk to him about it. I seem to be the only person he reaches out to for help. He lives alone and has no family nearby, I do not know them and have no way to contact them. i know he is desperatly manipulating me to be his caregiver, and have caught him out on some outright lies about any other help he may have, there is none.This person is a casual friend, not a best friend, lover or family, and I am in no position to take on the responsibility of him or his animals. I have tried detaching myself after offering alternatives to him all to no avail. Where do I go from here? Who can help? Please this is making me crazy.
