Hey Heidi!
Whites are great fun so congrats on the new pet!
As for foods that are toxic.. How about we talk about what you can give them instead of what you cannot.
Crickets, roaches, beetles, worms, moths, some spiders are all fine. Also, with adults, you can give them an occassional pinkie mouse as a treat. The orange square should be fine if it is designed as cricket supplements. You can also use a piece of vegetable in there. The frogs will leave it alone, but even if they did not, it wouldn't hurt em.
How big is your frog? One thing you will have to watch with the whites.. they will get obese fast if you keep alot of food in their tank. They will eat everything you put in front of them. So.. a dozen crickets at once is not really the best way to go about it. If you have 1 adult.. I would put 3-5 in its tank every other day.. that will be more than enough.. or you can do 1-2 every night..
Anyways.. there are several whites owners here.. and all are great people that are very helpful.. so.. if you have questions.. ask away..
Tim
