Hissing at food?

So I've noticed something Dean has been doing that I probably just didn't notice before when it comes to when I feed him a cricket.
I've been seeing him "hiss", breathe, "say" boo to a cricket when he thinks its there and he is trying to make it move. It's actually quite entertaining because I do envision him saying "Boo!" to scare the cricket to move. Anyone else notice this?

Also do they have relatively hard time seeing sometimes? I've noticed when the Cricket is white from the dusting and its on the white paper towel that he doesn't seem to notice it is unless it moves which is why I think he does what I explained above.

lol that is awesome, my little charm eats millies but she never hisses at them, but i have noticed that she doesnt seem to see them some times when they are on something that is around the same color as they are. and they definitely have to be moving for her to look at them at all. it drives me crazy some times. lol

I know! Sometimes I move him over near them, or poke the crickets with a stick so they move <.< and then he eats them. Just so they dont attack him first you know!?

HAHA, I have seen that and then my leo usually shakes his head and looks around like "What in the world was that?"

my blizard coffee go nuts over her meal worm's and most the time she can see it but she got bad aim lol and kinda pushes her nose down onto the kitchen roll but the mealworm has already run away its kinda amuseing i think u silly girl... she went for me finger the other week thinking it was a worm lol

Lol yeah my Dean does that too, when he is in "feeding mode" any movement I make outside the cage he follows so I try to be veryyy still so I can watch him

yeah coffe dose that lol x
