Brown/yellow chunk on leaf ... PIX

My poor baby has this brown spot on it and I'm really unsure of what it is. I read through some other posts to see if anyone had any problems that looked like mine and didnt see any so i have no clue what it is. any ideas?

Now about 3 more have spots like that only smaller....no one has any idea what it is??


(and dont mind my kitty, she loves my plants as much as me!)
