I play a Khajit character in Skyrim... and I have two cats 
Hmmmm case solved. Now we only need @tebakutis and @Henry Dale to confirm.
I noticed that all my Instagram friends are either kajits or modded out girls... Maybe like 1 argonian in the mix
Full disclosure: Since you never SEE your avatar in Skyrim (especially not in VR) I chose my race purely based on the racial bonus, so I rolled Breton (25% resistance to magic). However, I wouldn't be a good test case for the cat owner = Khajiit player poll, since while we do have a cat, it's my wife's, and I've never owned a cat of my own (I'm 100% a dog person).
What do you mean you never see it? I play on 3rd person, I see my slim little Khajit lady all the time. Do you mean the fact you're wearing a helmet most time?
So I owned two/three cats (one lived with me but teeechniiically was my BF's).
Next character I do I'll probably take a breton, because I'd love me some magic resistance.
What's the appeal of water breathing if you don't mind me asking Henry? Because there are potions for that, but almost 100h into my game I never had to breathe under water for any dungeon... I can hold my breath long enough to go fishing. The mechanics of swimming are pretty horrible though.
But to answer the main thread, I'd say my favourite things are the crazy amount of things you can learn to do or specialise in. It feels like there isn't any mastering them all in one life. I love how the game is racist to you if you're not Nord, but minorities will bond with you, and how it guilt trips you into stealing from some good people...
The one thing I don't like if how every dungeon starts looking the same, always being an underground warren of creepy rooms with dead stuff in it.
Mind you I haven't met many hargraven or chaurus yet, so can't complain, but I wish there were dungeons that weren't all literally dungeons...
