I just got an image of a teeny tiny hazmat suit for Chewie. TOO funny! Patches/Bacon is SO adorable. I don't know how you could resist him, and if Chewie is the deciding factor, I would personally risk it and bring him along. As long as you can keep an eye on them both and could get them to the vet at the first sign of anything, you should be fine quarantining them together away from everyone else.
