Kinda off topic rant alert:
Which animals, under what circumstances, and by whom, are all factors in the slippery slope arguments about animals in public places. I think that sighted people who bring animals into public places such as stores, airplanes, or busses are mostly selfish and poor fellow citizens. They put their desires and needs above those of everyone around them. It seems to be impossible to impose standards of behavior for the animals and their owners, so I wish the animals would be universally banned.
For me, the topic is brought into crisp definition when the place is in an airplane, with close proximity, no escape, and insufficient air circulation. If the animal cannot wear a muzzle for the duration, or be in a carrier, then I think it should not be allowed in the airport or plane. If I am on a plane with someone who has a cat in a carrier, even if it is not close to me, I am miserable from the dander. This misery lasts for hours after I get off the plane. Cat and dog dander allergy is so prevalent, about 10% of the world population, that it just narrowly misses being categorized as an irritant. A classification as an irritant would allow more stringent public health guidance, at least here in the US.
I am a selfish person, apparently, because I am against animals of any sort in food stores and restaurants. The only exception being seeing-eye dogs for blind people. I greatly dislike seeing animals in restaurants with their front paws on the table and eating from the dishes. I am horrified to see animals in grocery stores in the grocery carts, or pooping in the aisles (I wish I were exaggerating). My disabled husband's intermittent and devastatingly violent diarrhea only cleared up when I began taking a separate big bag to the grocery store and put my food into it so the food never came into contact with a grocery cart. Hmm.
I am now prepared for the fertilizing storm of animated discussion.
