Just as I love my children the same but in different ways, so do I love my cats. (Of course I love my children more)
Children will throw up everywhere, jump on your furniture, poop in their pants, and wake you in the middle of the night with a high-grade fever requiring a fast trip to the emergency room. None of this will diminish your love for them. When my son was little he put Lego in the oven unbeknownst to me and when I turned the oven on, I had quite a flaming plastic mess to deal with. He also put a GI Joe down the toilet and completely blocked it up requiring a plumber's service.
Cats will throw up on your carpet, scratch your furniture, miss the litter box and poop on the floor, and wake you at inappropriate times. None of this has anything to do with how much you love them. You will simply clean up after them, all the while calling them cute little nicknames and singing silly songs to them.
The love of a mother is strong and pure and knows no boundaries.
