Sorry it took me so long to respond. Been busy.
Mosaic too is also my display snake, I did not expect her to spend so much time on her branches when she got older. But man every time I go to check in on everyone she's out just chillin, its awesome.
Yes she also is a great deal calmer outside her cage. I mostly am just practicing good cage habits with Mosaic while she is small because she HAS tagged me in food response and I am well aware the size she may obtain someday, I don't really need to be tagged by a head and teeth as big as my hand down the road.
She's quite honestly fine once I get the message across that its not feeding time.
Based on your question I'm thinking you're suggesting I have a tub set aside to hold my larger girls during cage maintenance?
