1. The great era of American Expansion began not in 1830 but in 1803 with Jefferson's decision to purchase the Louisiana Territory.
2. In the history of American expansion, 1860 is a meaningless date: the national attitude
toward expansion was the same both before and after that year.
3. The Vote on the Wilmot Proviso demonstrated how members of Congress felt about the
expansion of slavery.

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
