We already have a seven-month old kitten, and we're thinking of adopting a new kitten around the same age.
I understand that for some adult cats, even if you take all the right precautions in introducing them, they may never really get along, and actually end up being less happy in their lives than they would be if they lived alone.
I would like to know if this is a realistic concern for kittens this age, or if they always tend to accept each other. If there's a significant chance they won't get along, we may just forget about it.
The kitten we have is very energetic and playful. He's neutered.
I see that there's another question on a similar topic, but what's there doesn't really answer my question.
What is the chance of two kittens being introduced and housed together without improving their lives?
I mean that overall, in terms of the cats' happiness, they would be better off apart. That is, the stress of sharing the house with another cat outweighs any companionship. I think snuggling and playing is a good indicator of this, because if they're not friends, I only see a downside for them. The downside could range from a certain low-level stress (being wary of each other) to something more extreme (fighting).
I don't want to adopt a kitten, that ultimately decreases the quality of life for either or both of them.
