He's just not pooping

[Amphibious]

I've had my frog, Harold, in the range of a month. All of his behavior is normal and he has a voracious appetite. In this time he has not pooped once. His previous owner said he had never known him to relieve himself either.
I'm just confused. I've moved him from his cage to a holding tank when I cleaned his enclosure; I felt not hard lumps on his belly.
Can anyone give me an explanation on what is happening here/causing this?

Could be his temperature isn't high enough for him to be able to digest his food properly. Make sure the temperature is accordingly 80-85F with a few drop of degrees at night. Do you have a water dish in the enclosure if he prefers to relieve himself in there? Try keeping him on a softer diet of just night crawlers for now and watch him. You could also soak him in a warm water bath for 10-15 minutes, this usually helps peoples frogs poop. Make sure his food isn't staying in his stomach to long and decaying. Could bloat and die from this. Keep an eye on him and spot clean the cage when he move for signs of poop in the dirt.

I agree, warm soaks and diet variation may help poop. If it continues I'd take your frog to a vet. When mine was impacted they prescribed some laxatives that I would have to squirt in his mouth. It was difficult but eventually he pooped and went back to normal.

Good luck!

It must be the temperature. He actually is on a diet of nightcrawlers.

Agreed. Soft diet, warm temps, and soaks in lukewarm de-chlorinated water.

The regimen starts immediately. He's emerged from his burrow and is quite bloated. Hope I can fix this.
