Science- How can you test a hypothesis if it is not possible to do a controlled experiment.

In a non-experimental hypothesis test, a researcher predicts observations or patterns that should be seen in nature if the hypothesis is correct. She or he then collects and analyzes data, seeing whether the patterns are actually present.

explanation:

wow this is going to be a long one

cats shouldn't be kept inside their whole life they should be out in nature in the fresh air but because of our technology advances it has become unsafe for our furry friend to be outside in the city's, because they could be hit by vehicles. in city's yes i agree being inside isn't the worse thing, but if you live somewhere rural you should let your cats outside, yes some animals hunt cats but i don't think cats should be kept inside confined to such a small space.

btw this is my opinion
