You need to know that the animal kingdom is sick of the gross actions of humanity and the abuse they have given to animals and they are tired of getting fixed by having their balls cut off and they would like vasectomies so they can continue to have sex. Animals have feelings too and that is the way God created them and evolution would not ever produce an intelligent species and the only evolution I have ever seen is when birdies poop out seeds and when bees cross pollinate.
