Another Clyde

In my mom's family, there have been some orange kitty Clydes. One of my YW leaders, a really cool person, offered me one of her new kittens! They are all orange, and so, on behalf of the cycle, I will name him Clyde. The only down-side, is that, Spencer & Dad, are ALLERGIC! And our family, isn't really a pet one. All of our pets have died...well...terrible ways. But I am going to be most protective! I have no idea how I can keep it, for my backyard has no fenced off places, and the mountain lions, bobcats, and coyotes will most likely eat it if I leave it outside. If you have any advice, please tell! THANKS!
