im sorry , i dont live where you do. but in my country, these are everywhere.
you can find it in "farms shops" ? these aren't pots for growing plants. they're for animals. so you might have better chance if you go to animals shops. so good luck

about the hidings. so far i made one hiding "small one!" i showed her the entrance. now its been more than an hour and its still inside
but i'll put 4 hidings

btw. i think i've put too much bedding wood for her. is that a problem?
