This can happen from stress, and also because Onyx isn't neutered, he may be doing this to show the home is his territory. I'd definitely have him neutered, and use a Feliway diffuser in the home to see if that helps settle him. Cleaning up the marking areas is tough, but I recommend using Skout's Honor cleaning products to get rid of the smell. I've found them to be effective. You can get them online or at a pet store. I hope this helps!
