Mice are used in lab tests all over the world. But why should they suffer this pain?
In the United States alone, more than 100 million lab mice are killed every year. Some of
them are slowly poisoned ( 毒害) to death. Some are placed on hot plates, heated to 60℃，to see how long it takes for them to respond to the heat. Some are given deadly diseases. Some have holes drilled into their skulls (头盖骨) for brain experiments. And in some experiments,
mice' s tails are cut off without painkillers.
Mice are mammals (哺乳动物). They have nervous systems similar to ours. They also feel pain, fear and loneliness 一just as we do. Mice are social animals. They also love their families. They“talk" with each other using sounds that the human ear cannot hear.
Although lab mice suffer as much as lab dogs and lab cats, they are not given as much protection as the dogs and the cats are. I abs can use as many mice as they want to. They don't
even have to count the mice they kill. Few of them are looking for modern alternatives.
Perhaps you can help make a difference. Do not support companies that test on mice or other animals. You can let more people know the facts about lab mice by setting up open classes in your neighborhood. Also, you can ask the local labs to think twice before doing experiments using mice.
