Hello again, I posted previously about my lovely five-month-old Siamese littermates (boy and girl) and they seem to be socializing well. At five months, I can pet and hold them (but only when they are in repose, I have to be somewhat slow and crafty to pick them up and pet them for longer lengths of time) and they seem to be more comfortable around me and my mom. Not cuddly by any means, they are quite adventurous and active, so I've come to get used to their states of relaxation (which is when I can pet them or pick them up) or high-energy craziness (when they race around the room, jumping over and at each other, climbing to hard-to-reach places, etc). However, I've done research and can't seem to find the answer to this question. I read somewhere that kittens (even Siamese) only vocalize to each other. I've certainly noticed this, as the cats will call to each other it seems (there is a quite distinct sound), because, for example, when one is not with the other, the lonely kitty will meow distinctly, and the other kitty will join him/her. But I don't think they are meowing at me yet for any reason. So first of all, how old before a cat is no longer considered a kitten, and most importantly, is there any age at which they tend to start "talking" to humans? I realize the littermate situation might make it a bit different since the kitties seem to have formed a stronger bond with each other than to their humans (me and my mom), but any help/advice would be appreciated. Thank you!
