Well my confused friend the answer is yes you can felt cat hair. But it takes patience, perseverance and a LOT of cat hair. And by a lot I mean more than you have there!
I recently brushed a massive ball of hair out of my cat’s fur
I have never felted anything in my life before and have no idea if cat hair can be felted or even what the first thing to do in felting is.. Here’s where I am so far... any ideas? Or throw it in the bin? Not that I have any ideas about what to make it into. Currently it’s providing support for a crystal ball but it’s very loose and sheds hair like anything. It got a bit wet and started to come apart so my guess is that it mightent work but then people make wool out of rabbit fur so... why not?
Confused in London.
I haven’t tried wet felting cat hair but I have needlefelted with it. It continued to shed until it was very very very firmly needled. I would expect to needle the amount I see in the second photo down to about 1/3 of the size it is now, maybe further.
Still it looks like you have just the cat for providing lots and lots of hair.
You can get needles at one of these places in your side of the pond.
