I am a little worried about my pacman frog. He has only eaten one cricket in the last four days. He is still active, has regular bowl movements, his temperature and humidity are normal, and he is not estivating, so I am not sure why he won't eat. He bites at the crickets but he won't actually eat them. Normally he eats alot more. I've had him for over five months now and he has never gone this long with out eating. I can't find any specific information about how long they can safely go without eating. All the books and websites vary Alot in how much they say to feed them.

How long before I should take him to the vet? I don't want to take him there if he isn't sick, but I'm woried about him. I would appreciate any advice! Thank you!
