how big was the leo and how large was the cricket? If it swallowed it fine I think it should be ok and you can stay on his/her regular feeding schedule. if it had trouble swallowing it than I would lay of feeding it for a day or so. Just make sure it swallowed it and its not stuck in its throat.
I agree, as long as it swallowed the cricket okay, then it'll most likely be just fine. The reason it didn't want to eat another one is beacuase it most likely got full on just that one
