I examined my dog's nose to see if dogs had nostrils or just a smooth, uninterrupted surface. It turns out she does have nostrils.
I told my dog I wouldn't want to be breathing through a dog's nose. I would be polluted by its body.
The cat also has nostrils. I told the cat I wouldn't want to be breathing through a cat's nose. I would also be polluted by its body.
They told me, 'We wouldn't want to breathe through your nose either.' I halfway expected that.
I told them, 'Hey, my air's OK.'
'Ditto,' they said.
