Dear Buster and Baby, aren't you the most adorable kitty siblings.
You two are inseparable and will call for each other if you are not in the same room. You, Buster, let your sister go ahead to get into all kinds of things before you try anything. That's very smart.
Together though, you are wild and wonderful, just like kittens are supposed to be. Eventually, both of you tire out, and then it is nap and cuddle time.
Buster and Baby, you are too cute for words, and I wish you and your family a great day full of celebration, and many more happy and healthy years together.
