Presently I have 6 ball pythons. Until I buy another rack, that is how many I can take care of comfortably.

I have no desire to keep 30+ ball pythons. Well, OK, I'd love 30+ ball pythons but I don't care to clean up that much snake doo doo. Nor do I care to breed that many rodents, and I've ended up doing so because the rodent supply in these parts is pretty unreliable. Some of mine won't eat ratsicles, I really hate cleaning up after rodents so that is another limiting factor.

Ideally, if I didn't have to raise rodents for them, I could see myself keeping 20-25 adult ball pythons without it becoming a chore. I'm 56 years old and a lot lazier than I used to be so I can't see myself keeping any more unless I hit the lottery big time and can hire servants to clean the tubs out.
