Our tortie kitten has some perceptual misconceptions regarding mirrors. She is a determined little thing who loves to be with us, and who, if separated from us by a door or window, paws rapidly on whatever is in her way as though to scratch through it to get to us. Sometimes we even open the barrier to let her through. She does the same to mirrors, as though there is a room just beyond her reach. I notice this the most in the bathroom. She sits on the counter and paws and paws.
I suppose it is an easy mistake to make, since a mirror and window glass feel the same on her paws, and she can see things beyond both.
When have you wanted to be somewhere you couldn’t get to?
