Cactus lovers/growers?

Fredwina,
Is that the view from your prison cell window?
(just kidding, I lived many years in PR and got used to all the essential "rejas" over every door and window there)

Actually, it's parkling lot for the train station in Upland. You can see the tracks if you look close.
And a question from Cacti newbie:
They're currently sitting inside on my window sill. would they do better outside? I'm worried about birds decding they look yummy...
