Groomatic
Sure, you could spend about $45 to buy this automatic cat grooming machine that looks like a tiny, white cactus jutting from your wall. And sure, maybe that would work on some cat breeds, like the short-haired ones in this video. But as the owner of a ridiculously floofy cat myself, I can confirm that this sort of thing wouldn’t do anything to get out the usual lumps and clumps that come with being ridiculously floofy.
That means for me (and tons of other cat owners!), buying something like this would be like buying a $45 petting machine. And frankly, we can already pet these beasts with our hands. And we can do it for free.
