I just fed my three FBT's like 5 mins ago and one of them caught a cricket in it's mouth as well as a pebble. the cricket escaped, the the toad still proceeded to eat the pebble. I tried grabbing it out of his mouth but he swallowed it! Now he's just sitting on a piece of wood and the sides of his stomach are twitching. is there anything I can do? do frogs barf?
