I agree - looks to be an ad from the 50's. Also, thank you! I could not remember if it was the Woolco, or Kmart store in Windsor that sold the squirrel monkeys etc. I also remembered the Mynah birds, and especially the Toucans! I was telling a younger co-worker of mine about that pet dept just a couple months back, he looked at me in total disbelief. I don't recall the Capuchin monkeys, or the Black & White Tegus, or probably a lot of other things from back then. At that age I didn't make it outside of Riverside often, and I'm afraid that I never made it to pet store with Ocelots etc. That is insane.
That's right, I'd forgotten you were a local boy from that area as well!

Yes, it was the K-Mart in the far east end of the city (Lauzon/Tecumseh) which had all the cool stuff; Woolco was across the road, but I don't recall if they had a pet department. Oddly enough, I can't recall the name of the smaller store in the west end that sold exotics, or the one in the east end that had the Lemurs, even though I visited them often. The lady in the K-Mart pet department knew me and my family well, but I think she always got a bit nervous when I offered to help out when it came to handling some critter of which she was afraid.
That's why I recall the Tegus so vividly; a young lady was buying one for her husband, and the sales clerk was scared green of them, so I offered to grab one and stuff it into the travel box for her. Once I got hold of the thing, which I recall as being the approximate size of an adult Nile Crocodile but was probably a fair bit smaller

, it wrapped its hind feet around my left hand with with a horror-movie grip, while my right hand gripped the thing behing the head. The lizard was open-mouthed, squirming furiously and whipping its tail around like an Indiana-Jones bullwhip, clearing shelves of merchandise and leaving a livid welt across the purchaser's forehead. I have rarely worked so hard at simply trying to set something down in my life!
There was a Towers store in south Windsor that had a well-stocked and well-run fish department, sort of a franchise-within-a-franchise, operated by an older German gentleman who sold me many fish as I grew older and always had time to answer questions. He periodically gave me store credit on things I collected and brought in for trade; baby gar, hatchling Snapping Turtles and Painted Turtles, Red-spotted Newts and on one memorable occasion a small Massassauga Rattlesnake that my mother forbade me to keep for some silly reason.
There was also the seductively-named Mermaid Aquarium on Wyandotte, which would from time to time get shipments of newly-hatched sea turtles. I wanted one of those badly, but could never come up with the scratch for one, which was certainly for the best as I recall all of them as being on death's door when they were offered. A visit to Mermaid was a rare treat, as my mother disapproved of both the name and the hand-painted mural of a flamboyantly voluptuous semi-aquatic lady on their front window. The only time I got to go there was when I was out and about with just my dad, who frequented a nearby electronics store and also indulgently encouraged most of my interests and hobbies...and I think he liked that mural...
Insane? Yes...but a different world then...
