Give the ability to track pets

It would be really useful to add an item that allows you to track pets. Even though pets will follow you and teleport to you, they still can get lost pretty often. My idea is to add a collar with a bell on it. You could attach the collar to a dog, cat, or any other pet so when they walk it makes a ringing noise. The collar could also make the pet appear on a locator map, so even if the pet is too far away for you to hear the ringing sound you could just find it on a map.
