Happy Pets: NEW! Color Dyes for pets
Colors available are: Black, Pink, Purple, Blue, Green, Yellow, Orange, and Red. The dyes go for 18 Facebook Credits each, are for one-time use, and earn you 54 XP per use.
The dyes only replace the colors of the head, legs, and body, so markings -- such as stripes and patches -- will remain unaffected. Eye color, ear color, and nose color will also remain unchanged.
To change your pet's color, click on your pet, go to the "Dress up" tab, then click "Dyes". Or you can buy the dyes by going to the Store, the Accessories section, Clothes, then "Dyes". Right now, the dyes are available in the "NEW!" part of the Store. Check out the cat results of the Color Dyes below.
