Oh, siblings! If you are one of three, then you know that two of your sibs always seem eager to gang up on you at the slightest chance. (That was our experience as the middle child anyway.) In this case, two of these delightful fluffs of fur are trying their best to get the other fuzzball to play. Or react. Or show any type of emotion--even though at one point the sleepy kitten looks as if it is saying, "ACK!" when its sib puts two paws around its little neck.
They are awesomely cute, so enjoy!
