should animals be used for research?

Animals deserve to live their life freely. 
Here are reasons:
1. They didn't do anything to you.
2. Why put them in pain when they didn't put us in pain? Its our fault that we get sick.

Animals have feelings just like humans. we should not use it as it has the same feelings as ours.
it should treated like us
it is also a living being. does'nt it hurt for the animal if do tests on them 
it's wrong
they are our friends
friends lets help our friends<animals>to live a happy life
thank u
