Do cats not smell one another, even if they don't see each other? Feeby has always gone ballistic whenever she's seen another cat in the yard (with the exception of one years ago). My neighbor has a couple of abandoned cats, and one of them for whatever reason decided to spend a lot of today in my back yard right outside the screened in patio door. Feeby woke from her typical afternoon nap and went outside to her favorite water dish. The two cats were maybe 4-5 feet apart but couldn't see each other. I really didn't expect the visitor cat to react (she's really laid back), unless Feeby reacted. But, Feeby didn't react either. Instead she stayed away from the door? Feeby is 14+, is she losing her smell? Feeby has seen this cat before, and went nuts. I am confused, but delighted there was no confrontation.
