Lovely pics and videos
TBH, with those ages (all very young), I think things will work out OK pretty quickly. I too am a firm believer in Feliway and am one of the ones that got the good deal.
We have a rather nervy girl amongst our troupe called Ruby. We introduced Boris a month ago and she was very upset by his hooligan antics. Lots of hissing and spitting. No aggression; all fear bless her. He is now only 23 weeks.
Now she just shakes him off when he lands on her and walks off giving him "you silly little man" looks. I am sure part of the quick settling in process was to do with 2 feliways plugged in permanently but am also sure the fact that Ruby is not yet 3 years old helped too.
Am sorry to hear about Aimee
. Very beautiful girl
