My Albus will do the same, sit and look at the food for several minutes before he starts eating. Also, he seems to hate when i watch him eat. he will just stop mid bite and stare at me until i walk away. It's adorable to me.Sorry -
You asked a couple questions - here's my input
Personality: they tend to be shy as babies, Much more than sulcata , or any other I've raised. Cautious and slow ( unless running away scared ). I noticed this with mine., especially 1st 2 yrs. & she is still much shyer than my Sulcata's. As they age , get bigger, they get more bold.
Eating: My CupCake eats slow too. If I pick her up & set her in front of a piles of favorite foods like hibiscus flowers & leaves. She might sit there looking at it for 5 minutes before eating. Weird. My sully would've had it all gone by then.
Having said that. Others may have different experiences. Like all animals, they do have personalities ( tendencies ).
