Jasper has essentially moved in apart from returning to our neighbour for food - he leaves us about 6.30am each morning and is back for when I return from the school run, goes home again about 6.30pm and returns to us again about 8pm.
Every so often he disappears for a couple of days and it turns out he is spreading the love to another neighbour on occasion. His owner is being very pragmatic about it, we have agreed not to feed him, but she is happy that he is feeling less stressed.
In fact we were all agreeing yesterday that since he instituted his new staffing arrangements he was looking much healthier and the pulled patches on his back were looking better ...
... this morning he was in our living room and a big black and white cat who I've only seen once or twice before strolled through the garden. Poor Jasper got in a right flap, growled, howled and then when the other cat had gone retreated into a corner and pulled loads of fur out 
is there anything we can do to help him?
