Here's another one to add if you think it's appropriate: I bought this from Amazon US recently as I received a lovely Amazon gift voucher which was in $. I found I couldn't get cat / pet supplies shipped to the UK and wanted to get something for Mouse rather than myself. I opted for a Nerf Gun (despite hating having anything called a gun), because I had read quite a few posts here on TCS about how other peoples cats loved to chase after the darts...... and now Mouse has joined the gang.
