What happens to animals during animal testing?

They'll get injured and will face many difficulties . :(

-P!KACHU

Animal testing can have many different effects on an animal depending on the species, but these are the most common:

1. Loss of life

2. Impared hearing or other senses or complete loss of them

3. Impared movement

4. May cause the animal not able to reproduce which may lead to extinction if the animal is already endangered

5. disfigurement of body or parts of the body.

All around not a good idea.
