It would be ok to test on mice and rats cause they're annoying.

And besides we put traps and things like that already.

Things we need like medicine would be ok to test cause if someone was sick and they didn't have anything that would help you, you would be in trouble.

But things we don't need like make-up you shouldn't test.

So if you're gonna test on animals test on rats or mice you could also test on monkeys cause the animals closest to humans.
