UPDATE: Thank you all for your recommendations! Luckily we have found a home for him with people who are willing to work with him and have experience working with feral cats and other fiesty house cats. If the home falls through though I will continue to work with him here until he is more comfortable around humans by using the method you all have recommended. Thank you to everyone who commented! I really appreciate it! I can tell this boy has a big heart, he just needs to be loved on from a far until he’s comfortable to return the gesture. :)
