Visitors, but fur who?

What are you doing Einstein?
I think the Angels are back again Buttons. I thought I saw them 
go in back of the toy basket
Cool. They really helped you last year when you were
tiny and sick.

I don't see anything.
They are hard to see. You have to kind of look
out the corner of your eye.

You mean your purripheral vision.
You do know they will only be visible if they want to!

Let them try Timmy. Keeps them from under fur.

That was close Angela.
Naw, Einstein is now over a year old. No more 
Kitten vision Angelo.
Do you have who we are here to help this year.
Sure do. And he needs our help too!

Hey! I heard that! Hmm... Wonder who they are here fur?
Mums the word Timmy.
No problem Angels. I think I know but will zip my cat lips.
Thanks
