Yep absolutely seconding this one. Everything is very much a play-as-you-want playground, with many ways to level and a low stress, community based world. Pretty much everything that causes friction against other players in other MMOs (kill stealing, limited resource mining, open world pvp etc) just isn’t in the game or in its own place you don’t have to go.
I will say that it has a lot of complexity and systems on systems that have built up over time that can be opaque and overwhelming. But again, you have the choice not to engage, and can do perfectly well running your character around maps exploring and picking cabbages and pumpkins and doing whatever you think looks interesting. Just remember to change out your armor and weapons every few levels on your way to 80.
There are definitely cats that need companionship and lots of socializing, but there are also cats that are perfectly content with an hour or two of your time, and cuddling in and lying on your bed with you while you sleep can also fulfill that need. 40 hours a week still means plenty of time with you physically in the house. I’ve had cats all my life and seen lots of personalities. I think it’ll be important to find the right cat but they are absolutely out there. I say go for it.
