Long story short, stbxh is collecting his old girl cat at the end of March. I have a 5 year old boy cat who has known her all his life. They're not snuggly, but he likes to chase and play with her and just be near her. He likes company and is a bit sad on his own.
I have no control over any of this, but what can I do to make things easier on him? Getting another cat isn't an option at the moment but definitely something I'm going to do further down the line.
