I have always heard that orange males have the sweetest dispositions. Another tip for a laid back cat is to literally lay them back in your arms and see if they will allow you to hold them that way (like a baby) Our sweetest and most gentle cats are the ones who would let us hold them like that. You may get scratched if they DON'T like this though! Please let us know what happens with Cinnamon, OK?
We've been doing that with Blueberry since we first got him, lol. He doesn't seem to mind that much though.
There are a couple of options. Keep the kitten and get her a playmate so she won't be bored or ask the shelter to let you switch her with an older cat (a teenager perhaps, one who has already been spayed/neutered and has calmed down). I wouldn't worry about bringing the kitten back because kittens are easily placed (EVERYONE wants a kitten). You can also "kitten-proof" your place till she grows out of that stage, which she will eventually.
Yeah, everyone comes for kittens usually. So I'm sure she went to a new home already. We saw this beautiful cat at the shelter, she's about 2 years old. They found her on the street. The lady said that she'll call us back to tell us how she does with other cats. But she hasn't called yet Maybe I'll ask my dad to call her, or maybe we'll go to petsmart again this week
