When I got my mosaic female Dutchess about a week ago she crabbed a little bit. But I constantly have her with me, on night 1 i was offering her food by hand, if she crabbed I would pet her while she was in the pouch. Night 2 I let her explore leaving her cage door open allowing her to come out into the glider safe room. she was skiddish at first if my wife moved too fast or sneezed she would jump on me and crawl under my shirt (tiny nails leave lil red dots everywhere)
To make a long story short she crabbs now only when someone not in my family tries to touch her and is sweet as can be!
Yeah they can draw blood thats for sure!
Don't try to force your glider out of it's pouch.
Handle, care, carress, play, love your glider and it will in return love you back.
Dutchess get excited to see me, wife and 4 yr old daughter.
And loves to go out with us!
