Went by local pet store @ lunch, they had a used 18x18x36 for 29.99, I couldn't resist! What timing I will now be able to put lil Phineas into that instead of a 2x2x4 of the bat after his lil home now.
True I could of put him in the 2x2x4 I have out in the box still, but did not want to be the guy who posted my cham fell from top branch 3.5 ft and has to go to the vet. No, I would rather it be more inline with their size. This way the branches etc can be put in that are appropriate for them and not worry so much about a fall from the top branch thats to big for them to grip good.
I had my guy in a 12x12x18 till 4 months then went right to the 24x24x48 I wish i had a medium cage to get him outta the baby cage for 3-5 month.. but i would of bought it regardless of needing it!
