If the income elasticity of demand for a good is negative, it must be an inferior good.

Explanation:

The income elasticity of demand, in economics, measures the quantity that is demanded for a good to a change in its income. Goods whose demand falls as income rises is known as an inferior good. Such inferior goods have a "negative income elasticity of demand".

Public transportation like an "intercity bus is an example of an inferior good" or service where due to low income, the consumer has to travel by bus but if the economy grows and the consumer income increases, consumers buy cars instead of traveling by bus.

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
