Pro and con of Animal testing?

Pros: Animals are less intellectually advanced. Animals are very loveable but we could use them so that we could eventually find cures to cancer and HIV. It can also help medical tools in hospitals. If you had cancer right now, would you want a cure? Or to die in a hospital bed.

Cons: animal deaths through research are considered unnecessary and are not morally different from murder. animals have the right to live there own lives, we shouldn't meddle with them just cause we can. the reaction of an animal to a drug may be very different from a humans so testing on them may be pointless.
