We did have two cats, 9 month old sisters. Very sadly one of the kitties has been run over. We'd quite like another cat at some point but is this likely to be upsetting to B? She got on very well with J but obviously the new cat wouldn't be her sister.
Is it basically just pot luck as to whether two cats will get on? I thought that as B is still young she might enjoy the company but perhaps I'm just projecting lonliness onto her because I miss J.
