He's taken against Tray 2. Not you. He is telling you there is a problem, and is confident you will fix it.
Sometimes one does wish they could speak a bit of English. :)
Why? Is Tray 2 new? Is he saying he only wants one tray or could he be panicking that a second tray means the arrival of a second cat? (I'm with you, I think this is it. He is very possessive of His Creature.)
