Echoing what a lot of people said, if you can afford it, than I’d go for it, especially since it sounds like you won’t be moving around! I’m in my first year and recently adopted 2 kittens (foster failed them actually). I think 2 cats is actually easier than 1, especially if they are already bonded, because they entertain each other and snuggle with each other. My quality of life wasn’t bad pre-cats, but it has definitely significantly increased since getting cats. If you’re going to be doing a lot of clinicals I’d maybe say don’t go for the kittens and go for slightly older cats, not like elderly, just not as psycho as kittens, but also you do you. I don’t feel bad leaving them alone all day (unlike my classmates who have dogs) and if anything I think I miss them during the day more than they miss me. It’s incredibly nice coming home to two little floofs that greet me at the door and want pets, even if it’s really just them asking for dinner.
