From the AZfamily.com:
[James] Gruver says the minute he made eye contact with the bobcat, it pounced. . . .
Gruver says he was, “Holding him with all the strength I had. There was nobody there to help me and it was either me or the cat.”
Gruver wound up suffocating and killing the bobcat. He still has several scratches on his arm but says he is just happy he survived.
