of a needle,the searing pain of a stubbed toe,and the throbbing of a toothache.We can identify many types of pain
and have multiple ways of treating it.But what about other species?How do the animals all around us
experience pain?It's important that we find out.We keep animals as pets,they enrich our environment,we farm many species for food,and we use them in experiments
to advance science and human health.Animals are clearly important to us,so it's equally important that we avoid
causing them unnecessary pain.For animals that are similar to us,
like mammals,it's often obvious when they're hurting.But there's a lot that isn't obvious,like whether pain relievers that work
