I am brand new and still learning how to navigate the site - I'm following tutorials and guides, but I would like to figure out how to change my second pet's color. I already have the dye, I just don't know what process to go through to use it. I tried going to the pet page and I tried going to the inventory and neither worked so I am stumped on what the trick is ._.

You need to go to the pet's page and then click the Genetic Philter button. You'll then be given a drop-down box which should allow you to select the Dye and you can then select the hex (color) code and the color which is being changed.

Excellent thank you!
