True, if there was not a demand for wild-caught mudpuppies, or any other animal for that matter, then people wouldn't rip them from their natural habitat. I fully agree with AnnMarie, not only do a lot of people neglect the animal when it isn't cool to them, but when animals are wild-caught they need to be treated often times for parasites and whatnot. Captive-bred axolotls are a better alternative for mudpuppies. Plus, I've heard that mudpuppies are far more apt to bite each others' limbs off.
Axie all the way man!
