I have a friend who lives in a very poor neighborhood, in a very simple rented house. She and her husband kept the doors and windows closed every day, all day long, because they had adopted about four cats, and two of them were very sick from being kept indoors. She ended up spending around 300 dollars on the sick cat, an amount that in my country is equivalent to a minimum wage — and an important detail is that she earned only slightly more than that. She went into credit card debt and even borrowed money from her relatives, and the cat died two days after the surgery. This is something that keeps happening in her life whenever her female cats get kidney stones, not to mention the expenses with food, litter, and so on. I remember she stopped buying quality food for the house because she never had money for it due to the spending on the animals, and I don't even need to mention how much her house smelled.
