I got bit by a veiled once,
bit my finger clean off...
be careful
chances are you have been stressing your cham the entire time that you "clean" things every single time of every single day. And any other time that your hand goes in there for what ever reason i.e.:move or water plants, feed, move or replace a thermometer. There is a ton of reasons to get in the cage for short periods of time every day. If your cham is running for spots they dont normally chill or trying to escape, then you might be trying to get them to like you too much.
Like that kid that no one wanted to be friends with in school because he tried to hard to be cool.
Not to be a jerk and call you that kid or anything like that but really, your cham does not/cannot choose to like you or not to like you. The sound or more vibrations from the way that you walk, the cars going by, your dropping or moving of things, the sound of you coming into the room, the scent of your skin when you enter the room, the sight of you moving and causing shadows in the room, the speed at which you approach the enclosure and the sound of you opening the cage and sight of you reaching in...
This series of stimuli can be specified to a "memory" of fear or a memory of a soon to end hunger. You want to be the latter if you want a "cool" cham. A chameleon that likes to chill on you because you mean food.
How old is your cham?
Maybe u jus got a broken one and need a new one tho bro.
Either way I suggest against gloves and socks or other "softer" "nicer" looking things to scare them with.
Just watch, very closely at the reasons your chams behavior changes.
