Alright! Wow!
@Nebari is up there....don't know how related the climate is.
I was just messin with you for information !
Livonia is in Michigan!
You have to be careful with cat litter, that Bonsai4me link is pretty well updated apparently.....if it's not in there, don't use it! IMO.
What you use will Probly be dependant on when you can water....
Once a day watering is a good goal to shoot for....it'll take a little trial and error, with good observation.
If you find the right cat litter.....
80% that and 20% pine would be a good place to start....
Wintering grounds.....that's gotta be tough for you.
