Turtle sounds good, a lizard of some sort, tarantula (dear god I HATE those disgusting things), fish, snake... Haha...I guess anything without fur or feathers.

Turtles can stink...I suggest an ant colony, like the ones they have under glass, hardly any maintenance and very interesting and educational to watch

how about a rabbit. as long as you keep them clean fed and watered they are good pets. food is pretty cheap aswell.

You'd better read up and rethink the Turtle idea! Turtles actually require a whole lot more (and expensive) things to PROPERLY keep them than you might think. Also, typically turtles bought at most places are wild caught. The people go to where the turtles live and STUFF THEM into Styrofoam picnic containers..they stuff them in too full and most of the ones on the bottom DIE before they are ever unpacked. Also because of the way they are kept they often develop respiratory diseases that YOU cannot tell they have until they become so sick that they usually die. In addition, if you do not provide the proper habitat for them to live in, the right temp, a proper type of light that is not cheap at all, they will also be subject to getting respiratory illness and will either suffer or die. PLEASE RESEARCH ANY PET YOU ARE CONSIDERING BRINGING HOME before you choose one. I thought about your conditions, set by Dad and to be honest one of the pets that most closely meets them is a Rescued Grayhound. I don't know about the cost to adopt, but they are beyond quiet most of the time. One or two nice walks a day (before school and again after school) would meet their "requirements" for exercise. They are about the most "couch potato" type of dog (breed) I've ever known and like nothing better than to lounge near you while you do your homework, watch TV, read a book. Yet, they are loving, appreciative of attention (a hand stroking them as they lay next to you on your bed, while you read over the history lesson the teacher has assigned for tomorrow!), they are fairly large, but gentle and truly slugs for the most part. I believe they are usually already neutered or spayed before adoption, and generally require only their yearly Vet visit for vaccines and a normal check up. ANY PET can develop health issues that would need to be Vet checked...just as you and I need to be seen for regular yearly check ups or dental work....owning any pet is a commitment to care and love (with many) but, the rewards are huge!

A rabbit is a good idea. Or how about a parakeet? You could always get a kitten. They are available all over for adoption and aren't that expensive to keep. They are also quiet and very independent.

snake. possibly a small boa. they are fairly easy to maintain, and when they get to about 2 or 3 feet they become very affectionate. i will own 5 when i get out of government barracks... grumble grumble...
