Our 4 cats were in and out 10 times this evening, playing in the snow then coming in for awhile. We've taught them to paw on the glass on the front door when they want in, so it was up and down, up and down for me!
A fabulous shot Lynn, how come you don't have a cat door? Minky is in and out all the time, I would not be able to sit for very long. The door gives her the freedom she needs ;-)
Haha, my Shibas do the same thing. I leave the back door slightly ajar so they can push it open when they want to come in, but I still have to get up to close it since its cold outside.
I'm really surprised your cats will play in the snow. I didn't think cats were too keen on any kind of water. Looks like you need a remote for the door like the kind we have for our tvs!
