we got the harnesses and leashes at Petsmart. The leashes originally matched the harnesses, but they grew out of the harnesses already! so we picked up some figure 8 style, which I like much better and they're more adjustable.
It does make me smile though to see a cat on a lead... hee hee, we don't get that over here, we do HAVE the leads/harnesses I think, but no-one seems to use them!!
Bod - I've got leads/harnesses for mine, but they either wriggle like mad and get out of them or they just sit down and refuse to move.
Actually, when I let them all out in my small back garden without leases, they just mooch around and dont really stray. IF they go out of the gate I walk out to them and they just come scurrying back in.
Ah, what it is to have well-trained kitties (I wish . . .)
Those kitties looks so sweet romping in the autumn leaves with this bright harnesses on!
