I am not sure about the spider thing my spider is a see-food eater.. I mean eats everything if I don't give her enough she wants my hand too. I wouldn't worry too much unless she is showing other signs of distress.

I am having one male at a time having feeding strikes over here. As soon as I got one eating the other one decided against it. It happens keep offering food on a regular feeding schedule. Thats what I did and then lo and behold he took it. Also bizarre twist my male mojave only eats female prey. Go figure.
