should i get a younger kitten to the 1 i have already does it really matter

i had 2 kittens, one has died. both kittens got on really well and played together all day. i now feel really bad for the kitten thats is left. she seems so heartbroken. i really dont know what to do.

If one is very much older than the other you'll have to watch the little one carefully because it may tend to start to harrass the older one, and the older one may not be too understanding. Other than that, its probably fine.

One thought, though: I had two cats that were not related but that became so close they would sit for hours together. One acted like she was the other one's mother. (They were two spayed females.) When the older one died the younger one went into what was clearly mourning (walking around "calling" her friend, waking me up in the middle of the night so I'd sit with her until she slept - but when I'd go back to try to sleep she'd come call me again). There is nothing you can say to a cat that has lost her lifetime friend, and the mourning in this case went on for months and months until Spring came and the cat could go outside. Even then, when she'd come back in she'd call once in a while.

I'm not sure I'd put a pet through that again. The little one will be lonely for a while, but she'll get over it. Pay extra attention to her, be extra kind and loving, talk to her in a soothing or else cheerful voice. It may be nice to get her a little playmate, but as with people, sometimes you can't replace the one that is lost. I now have another female cat in the house, but the two "girls" aren't particularly close at all. (The second cat I now have is because I'm caring for my daughter's cat. I wouldn't have tried to replace the older cat that died.)
