Snakes? What kind of snakes? My cat brought a snake home once. It got loose in the house and I never found it. There are coyotes a couple of miles south of me but they don't seem to come close to the more densely populated area where I am. If they did I would keep kitty in at night, or build a dome over the house. Actually the dome would be great for winter. kitty hates the snow and she would love a domed snow-less area.
