After reading about so many rave reviews about the Furminator, I bought one off of eBay. (That's where I found the best prices. It's not a cheap item.)
So I tried it out tonight. Loki's no longer blowing his coat, so there wasn't much anyways. But I still got much more undercoat fur with this than with his other brush. Yay!
One day I'll have his fur spun into yarn. It's really expensive, but one day, I'll have it done. Here's one site that does this.
