Walk-n-vest

This harness states it will work for rats and ferrets. The larger part of the harness was velcro and didn't even fit my rat's belly (I guess he's kind of chubby), but the smaller "neck" part of the harness was too big and was not very adjustable. He slipped right out and could undo the velro no problem. I am still on the hunt for a good rat harness, because my little guy would probably love some time outdoors. I may have to breakdown and make one myself because good rat-specific products are hard to find.

Pros: Seems fairly durable

Cons: Does not work for rats, as advertised

My fiance and I use these on our two ferrets and they work absolutely great for us. The only thing that sucks is trying to put them on our girls while they're squirming around.

Pros: They stretch to fit

Cons: It can be difficult to find the correct size since they stretch
