Yes it will attract bears and squirrels, mice etc. Someone earlier asked about storing it, you would be lucky not to find it strewn all over by a bear if it is not hung in a tree, also the mice and other critters will be into it. I graze alot , hobbles, and or electric fence depending on the area. I also bring rolled corn for energy and pellets for roughage so I dont have to graze so long., be careful with the pellets and make sure they are not too big. Our vet says judging by the number of choke cases you see he would not feed cubes without soaking them.
