if you are keeping them on dirt / coco fiber it does need to be cleaned! However not very often and not as much as a clean as keeping bugs on bare bottom cages require. I just remove some dirt every so often (where it looks most like frass usually) and replace it with new dirt. Its much easier and less labor intensive hah and not a dumb question at all! 

do you have any bright lights on when feeding? some leopard geckos dont see very well with bright lights (especially albinos) and the behavior you described is typically something my albino leopard geckos do when I have too much light on them during feeding. I also did have a non albino though who would bite everything thinking it was food... hes stopped doing that now but he was very enthusiastic about eating things 

we are all proud of her

I dont think it would hurt if they werent being lit. Though for reptile safe “smells” in our house we mix just dry herbs and put them out and about the house 

Beautiful misunderstood stickyfeet geckos If you wanted more opinions on one as a pet, I couldnt answer that as I have never had one lol

Thats awesome! Ours is still.... very lacking but the first day we went in there they had flies all over and there was PILES of feces in a dirty sandy cage. Last time we went they had clean cages, hides, and reptile carpet. A rather huge improvement to what it was 

Talk to the manager and complain, complain to the highest person you can there. I know it may not seem like it does much, but it does help send a message that this is not ok. The more people that complain the more likely things are to change. Recently our petco and petsmart have greatly improved on their practices (cleaner cages, no sand, more hides, ect.). They still do some things that are still bad such as cohabbing but its a big step in the right direction. 

very slowly. Leftovers are a great thing and yea fingers / hands go first
