Sounds like one tough cat...
Most likely though the code has the cat/dog outside on sunny/cloudy/windy weather days and inside on snowy/rainy/stormy days. I don't do code, but that would be my idea, seems like if you mess with it too much it could easily create bugs and glitches. I just ran into a bug on a different game, should have taken a picture... instead my daughter and I screamed and left the in-game area
. Who knew there would be scary things in Animal Crossing: New Horizons
?
Sure, the concept of glitch prevention seems lame but a cat that just sleeps inside all day would be the same...
Now if the cat could knock stuff over inside... maybe mess with the plants, than yeah, I would get it hanging out inside all day... maybe the inclusion of a litterbox
