Wow…that’s a challenge. Is there any chance this cat will allow himself to be vacuumed? My brother had a Maine Coon cat (well, at least he claimed it was) and it had very thick fur that was hard to brush, but the cat loved to be vacuumed and that sucked out the loose hair before it got to the matting stage. I know not all cats enjoy this process but I had to ask.
I don’t know if this would work, but I just heard about the LICKI Brush for cat grooming, but I don’t think there is anyway I could keep my cat laughing himself to death if I tried it: https://www.kickstarter.com/projects/1046165765/licki-brush-lick-your-cat
