You have already received the answer -- pax=pet should be pax=pet(), but I have a simple 
side-comment about style.  It is common Python convention to capitalize class names, IOW make 
this class Pet instead of class pet.  This is convention not a requirement, but it does help 
distinguish class names from ordinary variable names -- especially to others reading your code 
(as well as yourself a few days later).   ;-)
