Mitzi's purr - she's got the loudest purr in the world IMHO.

The little paw print on her nose. The way she chases her tail - still! It always cracks me up and she does it at least once a day. I tried once to catch it in video, but she's way too fast and I'm usually laughing too hard to hold the camera still.

I love the way she puts her paw up to grab treats - she never uses her claws; it's always a gentle tap on my hand to ask for it nicely.

Her little voice - she's using it a lot more now and the psychic said she would - she's finding her voice in the world! Her little mrrt's - she's chirping in glee at me at lot more now too and I just love it.

Her beautiful coloring, especially on her face; her fluffy white ruff and her white mitts (I call them her ice cream feet because they're tri-colored in different places - just like ice cream!)
