My Cats were rescues so they've hunted mice before. This riles up one Cat to extraordinary levels of energy whenever she sees this toy out.
They'll chase after this toy without end, and will continue even if they're tired.
Its significantly more durable than a feather toy, but it'll start shedding if your Cat literally tries to eat it.
My first one broke when one Cat started tugging the toy while the string was wrapped around a table leg.
It doesn't last a tug of war with a 12lb lump of muscle, it'll however survive pretty much anything else.
One thing you need to keep in mind though is that its exceedingly difficult to get a Cat to give up this toy once they catch it.
Go Cat knows what they're doing when they made this attachment.
