Looks like they're still babies. It's great that you kept them togther, fluboe. We have several groups of siblings in our herd, and they generally form a pretty close bond. Calli/Ozzy/Princess; Trixie/Dita; and Little One/Devil Kitty until Devil died all have very strong attachments to each other. The longtail family - Tiny/Junior/Fluffernutter/Pippi/Daisy Mae/Smudge/Linus are a pack of weirdos, though. We watched the six kittens being born, they have lived with us every day of their lives, and they're a bunch of freaks. Linus is terrified of everything that either moves or doesn't move, Smudge, Fluffernutter and Junior are OK if we're in a particular place but not anywhere else, Daisy Mae and Pippi are more or less normal, and Tiny wants to hang out in the bathroom all the time. None of them will curl up with each other. Buncha loonies.

Reality is that which, when you stop believing in it, doesn't go away.

English isn't much of a language for swearing. When I studied Ancient Greek I was delighted to discover a single word - Rhaphanidosthai - which translates roughly as "Be thou thrust up the fundament with a radish for adultery."
