frog getting fat

[GrifTheGreat]

So Mr. Frogbody my sorta newish pacman is growing pretty nicely. Today he was out of his hole early for him so I thought id feed him a 2 day old pinky rat. One of my rat mommas had 12 so I figure id cull the runt and sure enough Mr. Frogbody gobbled it up like it was the first time he had been fed in his life. I have plenty of rats as my boa collection warrants I breed my own and am wondering if one appropriate sized rat per week would contain enough calcium for his growing needs or should I still dust his dubia with calcium every other feeding or could I just give him vitamin once a week? He is still a baby id size him snout to vent at 2 inches.
I like frogs

Bad idea. Your frog will begin to develops health issues like clouded eyes due to a protein buildup in the frog's body. Also rodents contain a large amount if fat which will begin to cause obesity. You should only offer them no more than once a month. Blindness is not uncommon in obese Pacman frogs caused by rodents being fed to often and thus causing clouded eyes. Stick to the invert regimen and occasionally offer rodents.

Edit; Kitten beat me to it
