I have two 4 year old neutered outdoor cats. All their adult lives they have been in and out all day and generally in at night. We live in the countryside so outside is very interesting! Grey is a bit of a wanderer so every month or so she’ll be away for a couple of days then come back to home comforts. Orange has never stayed out overnight. He is always in for dinner and in bed til breakfast. Until a couple of weeks ago when he suddenly started staying out all night and coming home at breakfast. Can anyone think of an explanation apart from him being orange? He’s perfectly happy, no hungrier than usual, absolutely no changes to anything. Except he is suddenly nocturnal. I can only think he’s got a job as a night watchman somewhere…..
