DCat has just turned 1 year old, she is a beautifully natured British Shorthair, who wouldn't say boo to a goose.
Recently we have been having trouble from a neighbour's cat, who is much larger and very aggressive. For the last few weeks we've just had stand-offs in the garden and lots of yowling, but on Friday night the neighbour's cat attacked DCat, leaving her with a large gash on her paw-pad for which she is on pain relief and antibiotics. My vet's bill was nearly £200 
I really don't want to keep DCat inside after her paw heals, so I'm looking for any suggestions of ways I can keep thug cat out of my garden, or otherwise protect DCat. Any suggestions?
