Thanks, but the "CROC" thing did it for me. I thought the person was joking at first. I had already read up on the Iguana, and figured them really not to be a big deal.
But my fear of Crocs is so bad, that finding out it was true they were there in Belize, I actually became nauseous. Severely. I have never had any desire to see Florida, and refused to go to Knott's Berry Farm when they had the Alligator House next door to it (fearing one could get over to the amusement park).
I have a 20 year old African Spur thigh Tortoise named Elvis who weighs over 100 lbs - I am not afraid of all reptiles, but the fear of a Croc getting my dog brings me to my knees. Those things just creep me out! Oh, no no way.
Guess I am back to looking into getting a place where mom is (who hates my dog) in Palma Nova.
Ok, Spain is nice.
