DID a web search on sheila's posting of bobcats and housecats and found this:
Bobcats eat about two pounds of food per day. They prefer to eat freshly killed meat. If large prey is killed, the leftover food is covered with grass, dirt, often sticks, and the bobcat returns to the carcass before it begins to spoil. Carrion is only eaten if the animal is starving. The main diet of the bobcats consists of cottontail rabbits, jackrabbits, mice and rats. They also eat squirrels, chipmunks, skunk, beaver, muskrat, grouse, wild turkey and other ground nesting forest birds and their eggs. Bobcats also kill deer especially in winter when the deer is weak and close to starvation or when wounded or killed by hunters. When available bobcats will also kill livestock, poultry, small pigs, lambs and sheep, as well as feral and domestic cats. Although bobcats will kill housecats, there are records of the two species hybriding.
