Cat-Faced Spider (HELP!!!)

[Serhat]

I adopted this little guy (Billy) couple weeks ago and made him a little house which was a mistake because as I learned about them, I figured out that they need giant webs to hunt and to feel comfortable. I live in Canada, Winnipeg and I’m scared to let him back into the nature. He might not find food because it’s almost winter. I’m planning to free him on the corner of my ceiling so that he makes a big web and maybe, I can feed him time to time.
I don’t want him to die, PLEASE HELP.

I hate to be the bearer of bad news, but I have yet to find examples of orb weavers living through a winter to the next spring. They simply don't have the lifespan, regardless of whether they get cold or not. Of course, I have not scoured the entire internet, it's quite possible someone has successfully extended their life expectancy. But if I were in your place, I would release it back into the wild so it can make babies and produce the next generation!

Looks like a heavily pregnant female that should be released to lay her egg sacks.

Their lifespan is abysmal and she won't make it much longer anyway regardless if she's inside or outside.
