As you said, Homebody, snake tallies can vary a great deal. I only have a "few" retired snakes now, but years back, & in a much bigger house complete with my "rodent ranch" for $ support & ample sustenance, I had up to about 150 snakes for a while, when some of them had offspring (that's counting hatchlings). My more "permanent" number at the time (& for some years) was 85-90 snakes. I took in rescues: some were unwanted pets, but mostly native locals -mostly of the rattling persuasion- needing relocated or needing homes if not deemed likely to survive.
I was only half-joking when I called my house a B & B (bed & breakfast) for wayward rattlesnakes- mostly in the summer time, but I never knew- I got a call for a young speckled found in someone's woodpile one winter- I learned so much from working with him, & he was a real cutie. Believe me, 85-90 'regulars' is enough to keep one busy...especially since I had a job & other things going on too. When I'd do a snake program, I was always asked how many snakes I had, then there usually one wanting to know (with a gasp!) where I lived...seeking reassurance that I wasn't their neighbor.(I had no close neighbors & I really miss that house!)
