I bought a sling carrier by Outward Hound to see if Bogey would even let me carry him when we went out. I think I only pay about $25 since I didn't want to invest too much if he didn't like it.
Amazon.com: Outward Hound Sling-go-Pet - BLACK:... I put a harness on him and there are 2 clips, one in the front of the bag that I clip to the front of the harness and another toward the back that I clip to the top of his harness. Although it is pretty plain for a carrier, I lined it with fur for the winter. Now that I know he will let me carry him I would really like to get this one but it is on back order. I know my husband would use both if we wanted to take him out.
