M1-2-Kitten and Alice

Alice’s Story
‘Oh, you wicked little thing!’ cried Alice, catching up the kitten, and giving it a little kiss to make it understand that it was in disgrace.

‘Kitty, can you play chess? Now, don’t smile, my dear, I’m asking it seriously. Because, when we were playing just now, you watched just as if you understood it: and when I said “Check!” you purred!

Alice was noticed that 3 of the alphabet has been hidden in this picture. What are the words that can be in the alphabet?

“CAT”
