Sorry if this has been answered and I just cant find it anywhere.... On a pets profile there is a little heart that you can have pink or blue....what is the point of this since your pets gender is stated elsewhere? Also I created all but one of my pets so the names they have are their original names but some dont say legacy...is that because some other pet had the name first? And If so can I find the other pets somehow?

I believe the heart you're referring to is the likes button. Clicking on it will "like" the pet. You can see on your pets page (https://subeta.net/pets.php) how many likes a pet has under the Hunger and Happiness meter.

Pets created before Subeta's non-unique pet name update will have legacy names. Pets created after that update will not have legacy names. Here is a FAQ about the non-unique pet name update: FAQ about Legacy Names/Non-Unique Pet Names

If the pet whose legacy name you're looking for has changed it (e.g. a pet's name can be Bob with the legacy name Charlie) then there isn't an easy way to find it, I don't think. I believe the Subeta search is broken, but you could try it to find other pets with a specific name: link

Note that it's also possible to permanently clear a pet's legacy name at the Bathhouse pools as well as just hide the name from your pet's profile with CSS, so there will be some old pets without visible legacy names. I personally cleared all my pets' legacy names, even the ones I didn't change, so none of my pets have legacy names.
