I have a greater concern about the stress a new, young kitten would have on my old one. I've had her since she was a kitten, and she's just getting skinny. Rambunctious and fun and purrs a lot, but she's never enjoyed new cats. At her age, that's what's holding me back. Maybe after her time has passed, the new kitten will be appropriate, for me. I'm also considering the possibility of a psychiatric service dog, which would be incompatible with her, given her temperament.
