Wired Science has news on how mice show pain on their faces, just like humans… not really surprising. Here’s a quote from the article:
“It suits us to think that animals don’t have a real depth of feeling or emotion, so it’s OK to treat them badly,†Williams said. “Farming practices aren’t very sensitive to animals’ feelings. It’s convenient to just hope they aren’t feeling these things.â€
Yes — “insensitive” is an understatement. However, conditions are far better for animals on small family farms than they are in industrial meat operations. If you’re going to eat meat, buy from a small supplier if you can.
