Tamed cats don't wander off if you're holding a milk bucket

Hello.

As you all know, you can tame cats. That's great, but they sometimes wander off if you're not careful, which can get annoying. I thought it would be quite nice if cats did not wander off whenever you're holding a milk bucket on your hand. Because cats love milk, right? Anyways, if you have a bucket of milk in your hand or off-hand, your cats follow you just like wolves do, staying nearby and not wandering off.

It's a small thing, really, but I think I'd be a neat, little detail.
