i agree, i have 3 iguanas who were all adopted. here is each ones story...
max, my 5 ft guy, i adopted the person who had him didnt know what he got himself into, a week later he gave him to me.... that was five years ago.
brazil, a girl who i worked with, her child won him at a county fair about a year ago, she had no idea how to care for the ig and knew i had one so she brought him to me that night, brazil is about 2 ft long.
argentina... i took him in about a month ago,the family who had him didnt like him, they were scared of him, they gave him to me, and boy does he have one nasty atitude from not being handled.
its really sad to see people buying animals they have no idea how to care for then get tired of them and not know what to do with them..... i have heard of people here in this town setting igs on boxes at the animal shelter.
