Many thanks for all the replies, there's loads of great advice, and yes, we
are complete beginners at this.
To answer a few points, the spider is just over 8 mnths old, and female, so
she will hopefully be with us for many years to come.
As to handling, I have to admit that neither of us feel a need to, and we'd
prefer not to. Apart from both being a bit worried about how fast it can
move (the crickets don't stand a chance), we would be really worried about
hurting it. I put my hand in close and she rose up on her back legs almost
straight away, so I don't think she's very keen anyway.
I'll look into wether it's mold or web today.
We've named her Rosey - not the most original name, but it makes her a bit
more loveable to the kids ;)
Once again, thanks for all the helpful replies :)
