I had to post this video of Keiran and Simon. Poor cat! I'm trying to get Keiran to learn to be gentle but it is taking a long time. His idea of gentle is grab and pull hard. When I'm not behind the camera I do show him how to be gentle and I sure hope he catches on soon or Simon might disown me!
The other two cats just run away when he comes near but for whatever reason, Simon usually puts up with it. I think that eventually they will be great friends, Keiran just has to learn to be nice first!
