The only thing I can think of with regards to deer and cattle is " those !@#$ cattle won' t get out of the way when you need to shoot" . I run around 250 mother cows on the same land I hunt deer on . The deer won' t run with the cattle but they are both tolerant of each other. One time I had a steer calf knock my ladder down while I was in my stand and I had to shimmy down the tree. Thats not easy for a fat boy.
