You have all seen them, I can gaurentee if you own a hamster it will have come up at some time or another. Hamster leads/leashes. They look like a fantastic idea, take your ham anywhere without the worry, but they are TERRIBLE.
They are so bad for the hamster, they restrict movement and can crush their little bodies. Pulling them around is no good either. This post is short and sweet, I just wanted to take the oppertunity to say NO to hamsters leads. Grr.
