OMG, I can't even imagine what Mocha would do with snow. He shivers and buries himself in the covers when temperature gets to the 40's at night (that's cold here in Sunny California). I love the pictures and can't believe your babies can get out without big coat.
I just saw our weekend weather forecast, it's going to be 79

(okay, okay, don't throw those snow balls at me).
Last time we rained for a long time, I bought two pieces of sod for Mocha to go potty without getting wet. My girlfriend in Boston heard and she did the same for her babies. She bought sod and put them in the garage. Just an idea for anyone interested.
