Please look, rosy not moving quite

[Icefire]

my gf got a rosy tarantula, and she buried a hole in a coner until
she got the glass, she spined a web all around like to proctect the
entrance

she dont seams to go drink water nor eat.

is this normal behavior?

it began like a little circle closing each day or so, now she completly
closed her web,

thanks for respond
