I have taken Diamond foodshopping with me, to Walgreens, to Walmart, etc etc. No one ever says anything and if they see her, the make such a big deal about giving her love and attention. She is only about 2 pounds so maybe a lot of people don't see her? I attached a picture of the carrier I got. I just got it off of eBay for $20, I think it's just as good as any other carrier and I am sure she will end up going pee/poop in it one of these days so I didn't think it was wise to spend a fortune.
