I wasn't trying to be rude, but like others said, when one hears cheap, it brings up negative connotations. I've just seen so many examples of people either buying a cheap "tiny tank" for a betta. Or getting a cat and then just feed it. They don't take it to the vet, or get it fixed, or even keep it safe inside.
I was taught that if you can't take care of a pet, don't have one. My intention wasn't to be mean, I just didn't know if you would be willing to provide proper care when I saw "cheap".
As for advice beyond a fish or a cat, I can't help, the only pets I've ever owned.
