Hi
I wonder if anyone can help? I have two cats who use a dog flap and lately a neighbour's cat - which we call horse cat - has started coming in to our house. I was concerned for her welfare so rang the number on her collar and they said she was probably just lonely as they worked full-time but to shoo her away.
The problem is this - for the third time we have found one of our cat's fur all round my daughter's bedroom and loads of poo on the duvet/walls etc etc Today I have found this cat's collar so obviously some major fight has gone on. It looks like I will have to throw away a third duvet as poo is everywhere.
Is there anything I can do apart from locking my own cats in? Should I call the owners up again - but what can I say to them?

Any advice gratefully received
