I on occasion visit a shop in the Upper Peninsula where they have cats (more than 1- maybe 3...multiple anyway) they *try* to keep in a separate room (the shop is on the end of their house) but on occasion the cats manage to visit the shop- I was surprised the first time I saw that- since then I've visited many small independent shops that have their (Pets) laying around- I think that *I guess* it is the owners choice- but they should probably post something on their door letting people know before entering that they may encounter the animal- or their may be hair/allergens. it is not uncommon though to find these shops- on the other side of this 'coin' I was in a shop one time when a customer entered and before she got 5 feet inside the store the owner approached her and told her she could not come in because she wore too much perfume- *that one shocked me way more than finding a cat laying on a shelf!!!* this owner did not have the best reputation in the customer service- friendly area- but she sure carried some wonderful stuff.
