We're thrilled and so are our cats
I saw a similar product advertised on Facebook, so I came to see what was available on Amazon.  I'm glad I chose this one.  First, the wire bristles are very fine and get through to our cats' thick undercoats, reducing hairballs and shedding.  Second, the self-cleaning feature is life-altering.  Every hair comes off in seconds.  (We put it outside for birds to use in nesting materials.)  Third, and best of all, our cats LOVE this brush, so much so that I bought a second one so we could keep one upstairs and one downstairs.  One of our cats is very vocal, and she has been making a whole range of new happy-noises when we brush her.  This product is great.  Now please make one for those of us humans who have very long hair!!!
