Lucky is doing so well. I'm so happy he is thriving

He's growing up so fast. Now he climbs the side of his cage when he wants to come out or wants attention lol. I've caught him nibbling on his lab block, so I've weaned him off the kitten formula mixed with baby cereal and dropped the manual feedings to twice a day. Anyone know what age I should stop?

He's so fluffy now, and his little ears stick up. He's so funny when he's out, so active and wants to run everywhere. And I've lost sleep over him running laps in his wheel lol.
