Blew my mind when I learned the cheap stuff works exactly the same.

Oh man, you're totally right about that. I remember being so confused when I first looked it up and saw the 2012 date everywhere. In my experience a lot of online sources just copy each other without double checking. I actually helped a buddy of mine install a similar system back in late 2010 and it was wrapping up right around then. The timelines get all blurry though so take what I remember with a grain of salt. Always good to see someone who actually knows the real dates.

Got a colony near my old place. Two females turned into 14 cats in one summer. That's not even a full year. One litter can have four to six kittens. And they can get pregnant again like a month after giving birth. Best thing is to catch them early and get them fixed. Took us about 6 months to get all of them trapped and to the clinic.
