The meow!, the barks! is not for their grateful but for our help. Our help is their hope to get a little better life. But what have we do to save them? Nothing! They have feeling. Our religion tell us to be good to every living thing in this earth. The Quran teach the muslim how bad the effect of being cruel to animal. Animal is the true friend to human. They know how we feel. They know which time that they might needed to make we feel better. even they can't speak but they can act to show their feel.
It is impermissible to treat Animals bad, and the punishment is in the hereafter from Allah, but there is no bad or punishment in life, Also there is a reward from Allah for being kind to animals, Wallah A'laam.
Mishkat Al-Masabih concluded from "Bukhari" and "Muslim" to the effect that: "A good deed done to a beast is as good as doing good to a human being; while an act of cruelty to a beast is as bad as an act of cruelty to human beings," and that: "Kindness to animals was promised by rewards in Life Hereafter" (Mishkat al-Masabih; Book 6; Chapter 7, 8:178).
want more testimony for that word? let we see what also the bible said.
For what happens to the children of man and what happens to the beasts is the same; as one dies, so dies the other. They all have the same breath, and man has no advantage over the beasts, for all is vanity. Ecclesiastes 3:19
THEY WERE CUTE TO BE HURT!
DO THEY LOOK LIKE A BEAST?
IS THAT A REASON TO US FOR MAKING THEM HURT?
