One of my 9 months old kittens got run over and killed yesterday - we're all absolutely heartbroken. He was gorgeous.
His brother is really subdued, and just mooches around the house looking for him. Tears flowing as I write. I guess we just have to give him extra cuddles, and he will get used to being on his own? We do have an older cat, but she sleeps all day and doesn't have much to do with the kittens.
We might consider getting another young cat, I suppose, in a month or two, does anyone have any experience of non-sibling cats getting on really well?
