I have started looking on the web for stuff in the UK. The cut up knotted t-shirt sounds like a winner, and the dressing gown belt.
Soft toys have been a no no, from almost day one.
She does play and sound aggresive, but loves to cuddle (on her own terms). Sometimes even a cuddle can provoke a play growl, which ends up like a cry, as if she is sorry but can't help herself!
Thanks for everyones advice.
