I am sorry to hear you are worried about this raccoon and this black cat. Which cat is Einstein, the ragdoll?
My name is Rebecca. I am a veterinarian and will do my best to help.
The raccoon will stay around, as long as there is cat food to eat. Raccoons carry a parasite which can be given to your cats or to you, that can be serious, so I would try to get him to go away. One way would be to stop putting out cat food; if there is no more food he will move on and as long as there is food he will not leave. Another option would be to borrow a live trap from your animal shelter and trap him and take him for a very long car ride. If you only move him a mile or so, he will probably come back.
You can also try to trap the black cat, and take him to your local shelter. If he is too wild to put up for adoption after he is neutered and vaccinated for rabies, the shelter may just release him back into the community but again not too close to where you live or he will come back.
To trap the unwanted guests, you have to put cat food in the trap, so you will have to keep your cats, Einstein and and the other cat family, indoors or in a garage until they are trapped. The only way to trap them is if the only food available is in the trap.
If you continue to feed the outdoor family outside, and put cat food out, you will attract more raccoons and more stray cats. You might want to figure out a way to feed your cats in a way that does not attract other animals. The more stray cats that come around, the more risk of your cats being exposed to feline leukemia and other deadly viruses. They can carry fleas that can make you sick as well as your cats; 67% of cat fleas are positive for things that can make people sick.
Let me know if this is helpful and what other questions I can answer.
