I have a pair of Asian vine snakes. I have mine set up in a 40 gallon glass aquarium turned on one end to make it tall and have all kinds of fake plants for them to hide in, since they are diurnal, I keep them right by a sunny window and in the summer they seem to do fine(in the winter I use a daylight bulb to up the temperature)Temps are hot spot from the light in the low 90's and ambient temp of 85 in the lower part of the cage. I mist them twice a day because they do not seem to drink from a water bowl(though I have one in there just in case). As far as temperment my male is very docile and I can handle him without problems, the female is aggressive and will give an angry display and has tried to bite before. So it varies by individual snake. They do feed primarily on lizards or frogs, but yes that gets expensive. I wouldn't think crickets would be very nutrional but they have eaten a couple just because I wanted to see if they would, I tryed small fish in a water bowl when they had babies, with mixed results. My adult female will take live fuzzy mice, but my male never would and so I still have to force feed him pinkys, but he's used to it and has learned to eat when I put it in his mouth so it's less stressfull, but he is healthy otherwise. These guys are just really tricky feeders. Prey always has to be live with them because they are unique in that they have the best eyesight because of their horizontal pupils and hunt primarily by sight. I've noticed they are very aware of their surrounding outside of the cage and even got all defensive when I put a poster of a leopard within veiwing distance of their cage(I didn't think it would have an affect on them and have since taken it down) With babies you may have to start out forcefeeding them regardless of the prey item. It seems that they prefer to eat only once every month(you'd think it would be more than that as they defecate about two days after eating) as adults and they do fine with that(mine bred and I think that shows they are in good condition)with babies they will eat about every 5 days. As far as laws go they are technically considered venomous and so venomous laws apply, but most dealers are willing to sell them as nonvenomous, because they are considered to be harmless. I think you could own these with kids as long as they are in a locking cage. As far as handling them with kids, they are really fast and you have to hold on to them tightly, very flighty, I think you could show them to the kids, but not a good snake to let them handle. Also for the fact that children are smaller and so their venom could affect them more severely in the unlikely event they are bitten. I've been bitten with no ill effects. Hope this helps
