Lol i put Caesar in a tub when i was cleaning his cage last week.....he pushed so hard, he popped the snap lock off the top of the tub and pushed the lid back and sat there with his head on the rim looking at me. I put Caesar in a 4x2 when he was 2 feet. I put him in his 6x3 when he was probably close to 6 feet but i would have done it sooner but didnt have the caging. If i had to do it all over, i would just order 6x3 or 8x3 cages right off the bat and put the baby retic in here with a bunch of hides. As it sits now, i might have to order Caesar an 8x3 end of summer if he keeps growing. Ali is going to love me if i have one along with Pat's new 4x2x3 cage end of summer.
