After my mother passed recently, I took responsibility for her four cats—even though I already had four of my own. I did so because the other siblings wanted to just throw them in a shelter, even though a couple of the cats were in the family for close to 20 years. Those siblings are not animal lovers and refused to help with any of the cats. (Sometimes I think some humans should be thrown in cages or shelters instead; the ones who just have no compassion.)
In any case, managing eight cats is definitely not easy, especially on my own. They have different personalities, quirks, and annoyances. At first when taking them in, I became discouraged and overwhelmed by it all.
