They definitely can play games with you.. And work out your own limitations. A couple of things Mewan worked out were that she was quicker than any of us and that we would not pursue her down the drive (main road and always the fear that you could wind up leading the cat in to traffic - we try to discourage any thoughts of going that way and encourage the 90 acres of field round the back - as best we can). In bloody minded mode, she could play on this with the running a few steps from you, etc. Of course she would come to you or let you catch her in the end but it could be frustrating.
