my personal opinion on the whole live/frozen rodents is to NEVER use live rodents, my reptiles mean the world to me and i would never put any of them at that risk, what if the frog doesnt catch it right and the mouse fights back, what if the frog isnt hungry but the mouse is, ur pacman could be seriously injured/killed , ive seen pix of a bearded dragon that was devoured by a number of crickets left in the viv, and snakes with scars/missing eyes etc from live food, so i reckon a rodent could do a hell of a lot of damage to ur frog, it is also illegal (in my country anyway , Scotland) to feed one vertabrate animal to another..
the only time that i would consider it is with a neonate snake that will not start feeding otherwise, or a snake that has been on hunger strike for MONTHS, even then this would be after i had exhausted all other possibilities
just my opinion but i know it is shared with many others, i simply dont feel i need to use live rodents when i use live insect feeders for all my animals that will take them, and with my brothers python we simulate a live animal (well to our best abilities) by warming up the mouse and using tongs to make it move around, the snake will strike and constrict, especially if u make the mouse struggle a little with the tongs after it has been bitten (this is done outside the viv so the snake does not think anything coming into its viv is food, less chance of us getting tagged ha ha)
