I’m kind of laughing at your neighbor comparing a non-electric fence to a regular fence. No a bobcat should not crawl under that. I have a 17lb dog that tried to climb under my horse fence. The bottom wire is 9” off of the ground….yeah that sent him screaming and howling. I think our fence is set at 2 joules? We keep it set lower in power because it’s 5’ tall 5 wire fence. We only electrified the bottom wire to keep critters out and the top wire to keep the horses from leaning on the fence then the middle ones are not electrified. However, even a shock from those 2 joules makes my 1,000lb draft horses yearlings take off running. Based off of the trail cams the coyotes don’t like it either
