Well, ive been trying to kill a bobcat for about 5 months now. I dont know if all bobcats are extremely smart or just this particular one. but i have tried using bait, distress calls, etc. and this damn cat comes up on to the bank of my pond and sits there for about 10 seconds and looks to see if there is anyone around. One night i saw it on the bank but didnt get focused in time, and i went inside about 1hr 1/2 later and came back out and it had taken my bait while i was only gone for a few minutes. the distress cotton tail tape i bought seem to have worked good because i saw it when i played the tape. anyways good luck
