I have an albino pacman frog and I am worried he may be sick. He is still eating and moving around as much as he always did. But the right side of his body has become larger then his left side. I took him out of his cage and he still hops around and seems ok, but i am worried about his right side. He looks lopsided when he is sitting down. I dont have a picture right now, but I can post one if need be. Someone please let me know what is wrong (if anything) and what I can do to remedy the situation. Thanks!
