I have a 120lb German Shepard (not fat, just big) and my neighbors have a really mean white cat. One, day the cat was outside the fence hissing at moose(my dog) and i warned the neighbors that moose had never been around cats before and i wasnt sure how he would react. They assured me that if anything happened their cat would beat the crap out of moose. he was just laying there looking at the cat when all of a sudden the cat jumped over the fence. as soon as the cat hit the ground, Moose was up and i was trying to pull the darn thing out of his mouth. luckily the cat didnt die, but he never came over again. Moose never even barked just kind of sucked up the cat into his mouth. it was actually kind of funny.
