My cat's hairbrushes -not really complicated but more like mysterious. Someone gave me a cat and I had these three small brushes so I brushed him quite often because he would sit and stare at me: "I wanna be brushed". Then one I was using fell behind some stuff so I left it and grabbed the next one. It fell in about the same spot so I grabbed the 3rd one. Meantime I did a bit of spring cleaning but no trace of the brushes that I lost: huh?? Then the 3rd one disappeared so I used a fingernail brush.. but 3 days later it reappeared right in the middle of the floor. I had searched everywhere for it. Very strange.
