Since the case where a cat got their humans sick I’ve been thinking a lot about that.
The scenario I could come up with is people stepping over infected bird droppings and walking all over their home, getting indoor cats sick and themselves by extension.
And I’ve been thinking about mitigation. In this case, shoe cabinets close to the front door. And never wear outside clothes inside.
Probably overthinking it but I’d rather be wrong than being right…
