I used to have a cat the would beg to ride with me. If I said, "OK, let's go." she would climb up my pants leg and perch on my shoulder. I got her a harness and made a short leash so she wouldn't fall off, but it was never needed. She only complained twice. First ride on the street, she started yowling in my ear as I was stopping at a stopsign because she was afraid the ride was over. The other time, she started yowling the last block from home because she need to go to the catbox. She was a cute little thing, all black except for a white triangular bikini bottom between her hind legs.
