What pet do you people think is best. a cat a dog a hamster or a rabbit? or any other suggestions?

because i had a dog. then he ped away:( then i had two cats but they ran away:( then i had a hamster but he killed himself because he wanted freedom:( and now i have a rabbit. and i want to get one of these pets or keep my rabbit named sniffles. he is a white-blue-eyed lion head cross. the best pets were my cats. Lusafur and sabbath. (my brother named them) please dont feel offended by my cats names. they were good cats and they didnt hurt anyone or anything. not once. SO, WHICH ONE AND POSSIBLY WHY I SHOULD PICK THAT CHOICE. AND IF YOU HAVE ANY BETTER SUGGESTIONS FEEL FREE TO TELL ME THEM. I am an animal lover and i love all animals. (even scorpions) so....... SUGGESTIONS AND OPINIONS ARE OPEN!
