Start small and with limited lifecycle, and maintenance. since you will eventually caring for it, even though EVERY child says they will do the deeds needed, eventually the novelty of animal care wears off... I went with them to a good reputable pet store, where my daughter could see and touch... I wasn't into fish care, but, her very first pet were goldfish (short life span; toilet friendly; though we had a family funeral for our large backyard, where my childhood pets rested, lol!) Then, we graduated to a hamster, where more care was needed, which was great, she did well, but, remember they do nip, and you need to be able to care for, since they learn from your handling, too! And you need to change and clean cage, at least bi-weekly. I then went to a kitten, since they are independent, and only the litterbox cleaning, was an issue, but, a reward system kept her on track, like credit towards her next video game or music want, or special large item, like a TV, etc. We eventaully got to 3 cats, 1 dog, and an ailing Grandmother with Alzheimer's... Not that Nana was a pet, but, the abaility for my daughter to raise those small little animals was the ticket to her learnign compassion for her ailing grandparents, and taught her to develop skills and abilities in consideration, kind, nice, friendly, conversative, foresight, responsible, accountable, research, math, shopping for bargains, environmental and pet friendly... Yet, she might have forgotten, and i had to do some of the work, but, I had a system (recorded) on the refrigerator that if she failed to do her specific, written works tasks "her job," which made me have to detour from completing my tasks, she was assigned a not so pleasant task to complete for me, in addition. She hated my jobs, and after doing three really bad tasks, she learned fast to finish her job. One afternoon of racking and bagging, and setting out for recycling our 1/2 acre of leaves for the weekend, changed that "I didnt do it attitude." Another time, she had to help me sort out my overflowing closet, as my "assistant," who ran the stairs; bagged the clothes; took to the garage for donation; and loaded the car for delivery. Remember, I was teaching accountability and responsibility, so that she could be a responsible, contributing member in society... Yes, she cried, pouted, but, finished her tasks, and is now, finishing her degree in chemical engineering, and is now a Mom, herself... funny thing, I listen to her, as she sets out to describe how her daughter will learn good behaviors to be a great person, I have to laugh, because on that list is that "she will have a pet, when she is old, enough!" I asked her, "Why?" she said because it taught her to be responsible, loving, and every kid should have a pet, because pet poop is REALLY humbling....! I couldn't stop laughing.. that girl is a responsible nut! good luck in your decision, because a pet, teaches alot, even for the parents... LOVE!
