My vet explained to me that when he needs to isolate, it overwhelms everything including communicating with family. He cannot see beyond the need to isolate and get away. Nothing at all. It’s such a strong driver, that normal societal rules just do not apply. Will not text back, will not see anyone, will retreat. It’s a force stronger than anything else that exists. Me and his friends have learned to leave him be for a few weeks when that happens and then check back in, with a casual text saying hi and hoping he is well. Hope that helps @Brturner13
