Our rabbits live indoors, but during the nice months we take them camping and to other outdoor activities. To protect them we give Revolution Flea & Tick during the 6 months of outdoor weather.
Occasionally when we have a nice covering of snow, I wonder if anybunny might like to go play in it (for short time, it is cold out there). But I don't want to dose them for what might only be a couple of minutes, and at the same time I don't want them to get fleas.
I know there are no absolutes, but is it safe to assume that a fresh trackless covering of snow is flea free?
