Kyuss is a topaz rex dumbo.

Kyuss was from Shunamite rats in Newcastle.

I've wanted a topaz rat for several years, and was so happy when I was offered Kyuss, along with Warlock.
Kyuss, for some reason, was less readily welcomed into the big cage than Warlock. Carl, the alpha, seemed to take exception to him and attempt to bully him. This was likely due to Kyuss being a bit more shy and sensitive than Warlock. Fortunately, his torment only lasted a few hours and he was soon sleeping bundled up with everyone else.
My brother gave Kyuss the nickname 'cream-puff' on account of how stupidly fluffy and cute he is!

Right now, he is your typical baby rat; bouncy, demanding and into everything.

Why Kyuss? Kyuss is the name of the band Josh Homme was in before Queens of the Stone age. Thusly, it is the name I gave to the rat character I based on him, and I always wanted an orange rat in real life to name after him. Like Warlock, Kyuss had his name even before I picked him up.
