Any kind of pure honey will do the trick, I use Billy Bee when I need it. I wouldn't keep them near a vent because when the heat kicks on or a/c it will make the temps be all over the place. You don't want the heat to spike and you don't want it to get to cold. For the window as long as he/she isn't directly in front of it you should be ok, again you don't want the sun to make the heat spike. I have never heard a toad chirp to be honest but if the frog ends up being male you will know when he croaks, it's hard to explain what it exactly sounds like. If you go on You Tube you will be able to find some videos of pacmans making noise, there a few of them on there. When babies I feed crickets and small pieces of nightcrawler, and throw in hornworms, silkworms, waxworms, butterworms etc for treats if I can them small enough and continue with this diet as they grow. When they are able to eat them I give pinkies once a month or so and move up in size as they get bigger. Now that mine are all adults only one of them really gets triggered by crickets and I usually really have to bug him with them, but not all pacmans are like this, alot will continue with the crickets. I just got stuck with the fussy bunch. L.O.L But all of them like there big juicy night crawlers.
