I like cats. They hunt and kill. In particular they keep birds from defecating on my porch and eliminate rodents from my household. They are killers. Unless you go all cat lady on them.
They aren't children. They are effective pest control that costs little compared to paying for pest control. It's almost like our ancestors knew what they were doing when trying to protect their food stores by domesticating them. Or even more scary, God knew we would need such a creature to handle pests.
OTOH, they are still animals and will display animalistic functions. This includes reproduction. Our lovable kitten that was killing birds and rodents changed. She went into heat and was insatiable. To people that have seen this, it is understood what I mean. To my children that have never seen it, it was appalling. It did remind them of Ms. Miley and her twerking.
That similarity is yet one more reason to have pets. Your children seeing the animalistic tendencies of such people will only be understood if they see it from animals as well. The ability to deny these instincts and desires is what makes us different from animals.
Our cat has been fixed and she is lovable again. She still hunts and the rodents that were in the house we moved into are gone now. Some eaten, some escaped. I would prefer to live in a country setting where I can have a glaring. That will happen eventually. In the meantime, our children have seen the Miley function removed from a cat. You don't have to do the same thing to people. They can adopt a moral system like Christianity and they stop twerking.
