my Trigger hardly ever comes into the sitting room since Tosker joined us indoors, and that's over a year ago now
and if he tries to get on my lap, or be near me on the bed, Tosker comes rushing in and Trigger immediately leaves because he won't share
it makes me a bit sad, but Trigger seems happy enough, and if I tried to stop him being on his own it would probably stress both of us out - as it is if he is settled somewhere I can reach him I make a good fuss of him, but very very quietly!!
Sooty may go on keeping her distance from Frodo, and from you if Frodo is around, but it is too early, I think, to know if it is permanent - after hissing at him she has moved on to stage 2, which is basically avoiding him - stage 3 might well be her tolerating him, and who knows, she might even get to appreciate him
