Around this time of year, a lot of places are getting deep coverings of snow on the ground. Do your pets like to go out and play around in it? Have they even seen snow or know what it is?
Our cats mostly don't go outside, except for one who loves the outdoors as much as being inside. It has been a couple of years since we had a good snow though, so I doubt she really knows what it is. We don't let her out when it is really cold anyway, she doesn't like that.
