So I beautifully and masterfully edited a picture I found online into a reference for Kitty's collar :D Yes that is a rainbow bell XD

Features: Purple leather, 2 rows of chrome studs, rainbow bell (red, orange, yellow, green, blue, purple, pink)

The colour that outlines the bell and the colour of the part that connects the bell to the collar doesn't have to be exactly how I have done it, as long as it's a rainbow bell on a purple 2 lined studded collar then it's fine :3
