Furthermore, when the deer learn that you are putting out corn every day, they will tell their buddies, aunts, uncles, cousins, and casual acquaintances. Deer may not seem like a problem for people in areas of the country with low deer population densities, but rest assured that it is a huge problem in the Texas Hill Country. About a century ago, there was a large and thriving population of mountain lions in the Texas Hill Country. So in those happy days, there were rather few deer, and unprotected roses and ornamental plants had a reasonable chance of lasting more than just one night. Unfortunately, the mountain lions had a regrettable habit of spicing up their bland diet by eating an occasional calf, dog, or child, and this culinary habit was one to which the ranchers took great exception.
Deer are very much like goats.
They will eat practically anything, but they prefer the tender foliage of new growth on small trees, shrubs and particularly roses. Deer are also like goats in that they never seem to have eaten enough to fully satisfy them. Cows will eat for a while and then lie down to digest and rest. Get a pet mountain lion. Get a pet that resembles some other ferocious predator.
