Context
My fiancée and bought a new house and moved in at the beginning of the month (just over two weeks ago now). The previous owners were leaving the country and we opted to adopt their cat; a 5 year old male, ginger, DSH. While his territory wasn't altered the change in "ownership" - as well as the general activity of people moving in and out - was obviously a little jarring for him. After a few days he seemed to be settling in nicely; he's quite affectionate and seems very comfortable with us. He is primarily an indoor cat but he does like to roam around outside for a few hours everyday (the previous owners also used to make him sleep outside however we keep him inside at night now). About 3 days ago (June 14th) he went out in the afternoon and didn't return, which was unusual. We're in contact with the previous owners and they say that he has never done anything like this before. We were extremely worried and assumed something had happened. We sent out alerts to our neighbourhood (including vets and shelters), put up fliers, walked around several times a day calling his name. This morning (June 17th) however he strolled back into the house as though nothing had happened. He has no injuries, doesn't seem to be hungry, dehydrated or distressed at all (I'm assuming he just decided to spend some time at another house?). He is microchipped (EDIT: he is also neutered) but lacks a collar (growing up, my cats never had collars primarily for fear of them getting caught on something). Since his return we have fit him with a breakaway collar with a name tag and contact number. The previous owners tried to give him a collar but apparently he hurt himself trying to remove it. While he definitely wasn't happy with us putting the collar on him he seems to have accepted it relatively quickly although I'm worried about distressing him at all.
Questions
- What do we do to prevent this happening again? I'm assuming this happened because he still isn't fully settled with us? If so, is it something that should get better with time?
- Is the collar a good idea? I've heard multiple conflicting arguments about it. What about GPS collars, are those worth the cost and are they safe/practical?
- I've read that you can't really turn an outdoor cat into an indoor cat but I know that my fiancée and I are going to be extremely anxious next time he leaves, in fear that he disappears again. How do we handle this? Can we teach/train/encourage him to spend more time indoors?
Any advice would be massively appreciated - Two very relieved (but now also very anxious) cat owners.
