To all you cat lovers out there, I wonder if you could make any suggestions. I already have one cat who I have had forever, but in April I got an extra one. This extra one, Jack, belonged to my daughter in Australia but she wanted him to come here because he was terrorised by other cats and dogs round about. I did all the usual things to get the both of them together as seamlessly as possible: gave Jack his own seclusion room (which he still has), kept them apart for a time and just very slowly introduced them to each other. There was an initial spat but then things seemed to settle and now Jack has the run of the house and enjoys being outside. However, a few days back, Sam, the older cat decided to take offence at Jack and just started going up to his face and meowing from low pitched to a high pitched noise. I don't have a clue what is going on and hope this is not the start of serious trouble. I know there are loads of cat lovers on here and wondered if any of you could give me some advice as to what is going on. I would appreciate any help I can get as I want them to live happily together. Maybe this is impossible. Many thanks.
