This weekend my husband had to fix the tiles in the shower which meant pulling the old ones up, pouring concrete and then putting the new ones down. He got all the way to the point of smoothing out the newly poured concrete ... (you know where this is going) and left it to dry. About a half hour later he calls me into the bathroom to see that the wet concrete now had numerous little paw prints in it. It's like she waited for him to finish smoothing it out and then stepped inside and danced a bit.
I think we view natural cat behavior as psychopathic sometimes because by human standards, it's predatory and anti-social. I love all animals but I love cats in particular because they are often amazing puzzle solvers, interesting communicators and more often than people think, they are affectionate and loving.
