Thanks team, will have an investigation.
It seems to be the landing and stairs which cause problems. I'm guessing it's because Eddie has to get close to pass Trixie and she isn't keen. In the bedroom and other areas she is OK unless Eddie gets less than half a metre. Trixie has always licked my neck when we cuddle, not sure but I think it's a comfort thing as I raised her from a few weeks old. She's not done it with Eddie in the room since we got her. Last night she didn't realise Eddie was on the bed with me and jumped up. Straight away I gently pulled her to me for cuddles which she did. She looked up whenever Eddie moved but there was no drama. It was lovely to have them both cuddling
I do feel for Eddie. I know it's normal for the cats to put her in the place but all she actually wants to do is have a sniff. Trixie and Eddie both have a similar silly play drive so if they could get over this they would get along really well. Oh well, I can dream!
