Ask Him. God created animals to help us and He created us to help animals. Create animals to feel pain? Try again when your head stops pounding. Your ludicrous.
So the animals can howl and wail when they are being attacked and being eaten alive by other animals or when we are slaughtering them in protest.
Reproduction is either asexual or sexual.
Asexual reproduction can be very advantageous to certain animals. Animals that remain in one particular place and are unable to look for mates would need to reproduce asexually. Another advantage of asexual reproduction is that numerous offspring can be produced without "costing" the parent a great amount of energy or time. Environments that are stable and experience very little change are the best places for organisms that reproduce asexually. A disadvantage of this type of reproduction is the lack of genetic variation. All of the organisms are genetically identical and therefore share the same weaknesses. If the stable environment changes, the consequences could be deadly to all of the individuals.
Asexual reproduction is the process by which an organism creates a genetically similar or identical copy of itself without a contribution of genetic material from another individual. Bacteria divide asexually via binary fission; viruses take control of host cells to produce more viruses; Hydras (invertebrates of the order Hydroidea) and yeasts are able to reproduce by budding. These organisms often do not possess different sexes, and they are capable of "splitting" themselves into two or more individuals. On the other hand, some of these species that are capable of reproducing asexually, like hydra, yeast (See Mating of yeasts] and jellyfish, may also reproduce sexually. For instance, most plants are capable of vegetative reproduction?reproduction without seeds or spores?but can also reproduce sexually. Likewise, bacteria may exchange genetic information by conjugation. Other ways of asexual reproduction include parthenogenesis, fragmentation and spore formation that involves only mitosis. Parthenogenesis (from the Greeke SS'snos, "virgin", + S'ss, "creation") is the growth and development of embryo or seed without fertilization by a male. Parthenogenesis occurs naturally in some species, including lower plants (where it is called apomixis), invertebrates (e.g. water fleas, aphids, some bees and parasitic wasps), and vertebrates (e.g. some reptiles,[1] fish, and, very rarely, birds[2] and sharks[3]). It is sometimes also used to describe reproduction modes in hermaphroditic species which can self-fertilize.
The Book of Mormon actually explains it pretty well. There must be opposition in all things.
"For it must needs be, that there is an opposition in all things. If not so, my first-born in the wilderness, righteousness could not be brought to pass, neither wickedness, neither holiness nor misery, neither good nor bad. Wherefore, all things must needs be a compound in one; wherefore, if it should be one body it must needs remain as dead, having no life neither death, nor corruption nor in corruption, happiness nor misery, neither sense nor insensibility."
(2 Nephi 2:11)

If animals didn't feel pain they'd die a lot quicker than not. Pain is your bodies way of telling you to stop doing what you're doing. Sometimes it happens unintentionally, like if an animal gets caught in a trap, but without those pain receptors they wouldn't know that fire is hot and should be avoided.
As for homosexual relations, God didn't create animals to have homosexual relations. Animals live on a different level of intelligence than humans. They have basic instincts and pleasure receptors. If two male dogs have sex it doesn't mean they're going to shack up together and pick out curtains, it means one was exerting his power over the other through the act of sex.
