I was just tong feeding my whites tree frog and I kept hearing this noise. I thought I was hitting one of the decorations with the tongs but then I realized it was Frankie, he was making a snorting sound every time he took a cricket. None of my other frogs have ever done that. He is my smallest but most vocal frog in the bunch. He had croaked really loudly about an hour before I fed them. Could he have just had excess air in his throat when he ate?

There are no bubbles coming out of his mouth or nose, he's otherwise acting like he normally does.
