We have just adopted a 2 year old cat from a rescue home.  She had a
tough time early on from what we can gather, plus cat flu and enteritis.
   She went from the vets to rescue home, then a foster home where she
has been nursed back to splendid health, was spoilt to death and now
looks on top of the world, glossy coat, shiny eyes, happy to be stroked
and petted.  BUT - she is rather overweight, and although we can't take
her out yet (she only arrived last night and the foster home told us to
keep her in for 3 weeks until she has settled in) we are reliably
informed that she doesn't much care for outside.  So, once it is safe to
let her out, if she's not keen on going, would it be a good idea to get
a cat harness and take her for walks?  or are cat harnesses not a good
idea?  This is our first cat, so we are on a learning curve and want to
do it properly and look after the cat the best we can.

We are in the UK, in a small country town and live in a quiet area, but
have lots of cat neighbours - if this makes a difference?

TIA
