Or has a “second” home, what is it, do you think, that makes them come back home to you?
We have an 11 month old and she is fed twice a day, with an appropriate amount of food. But she is reeeeeaaaaallllly chubby. She’s neutered so not pregnant. Just fat. We live in a very quiet estate full of other cats and I’m tempted to post on our FB group to ask who might be feeding her 
This is obviously her home and she doesn’t stay out at night. Incredibly affectionate to all of us in the family. This is definitely her home. But I do just wonder sometimes if she’ll end up rehoming herself elsewhere.
