One thing I do know for sure is if you're going to feed it canned food, DO NOT LEAVE THE FOOD IN THE CAN. Scoop it out into a bowel. The metal lip left on the can after you take the lid off is very sharp and can cut the cat's nose or mouth while it's eating.
Also, and I'm not sure if this is a real concern or not but just a thought that popped into my head, if you're planning on letting it catch mice you should probably take it to the vet more often than usual to make sure no viruses or parasites get transferred from the caught mice to the cat.
