This Cat has no Claws - Amazing Spider-Man #30 (1965)

In a very special issue (not really), Spider-Man has to deal with a new villain in town, The Cat Burglar. His not much of a threat actually, his powers are mostly shinning a flashlight in your eyes and ineffective smoke bombs.  More importantly, there's a bunch of bad dudes dressed like they're from the foot clan robbing trucks with big DANGER signs on them. What do they mean to the bigger picture? On top of that there's Betty, possibly the biggest heel in these comics so far, dropping a bombshell on Peter and forcing him to make an important decision. All that and more fainting spells from Aunt May, this is an episode you must listen to!!
