For month-old ball pythons, I think 2 gallon containers would be all right, but they would outgrow those quickly, so it depends on how soon the others will be going to new homes. If you can't predict that, it would be better to go for somewhat larger enclosures just to be on the safe side. Also, how soon after transferring them before you feed depends on a few things, but if you were to move them today, you could give them just a couple of days to settle in to being alone and try feeding again (I'd say a minimum of 48 hours, but you don't want to wait too long since they've probably only ever eaten once).

Your "stupid foreigner" question isn't stupid at all. Maybe they're less common in Finland, or called by a different name. This page: http://www.drugstore.com/templates/s...sp?catid=28346 shows a bunch of human heating pad, but the type we're referring to is the type that plug into a power outlet (not the microwaveable, etc.) and that do not have auto-shutoff. Beyond that, you have a lot of options and a wide price range. If you can't buy them locally, I'm sure there are some web sites where you could order them already configured with the right wiring plug and voltage.

Enjoy your female (did you pick her out first thing? ) and be sure to upload a photo or two when you get a chance.
