I remember seeing a collared T-shirt with a logo showing a legless frog sitting on a wheel chair! I thought it was a little mind-provoking. But it does't seem like it caught the public's eye.
My dad used to catch frogs when I was in primary school and he'd bring home a few dozen frogs in rattan bags to skin and slaughter, which some family members were involved. The first thing that goes off is the animal's head, with one downward chop from a cleaver. The frog dies instantly, although its nerves may allow it to jump around for up to a minute even, (kind of funny). Then the paws an feet are hacked off, the belly is slit, and the skin pulled off. After these, a smaller knife (eg. kitchen knife is used to cut off the legs by severing the hips from the torso. The animal has to be completely dead by then.
Killing any animal to eat is never easy to look at. The best way for the slaughter is to make the process as quickly as possible.
Cheers!
Maybe it is also time to STOP eating FROG-LEGS too, since they chop out only the frog-legs and throw away the rest of the frog, no difference from sharks fins. Do the frogs suffer a slow excrutiating death after their legs are amputated?
