First time cat owner

Hello fellow tortie parents!

7 weeks ago, I adopted two 9-year old tortie ladies who’ve lived together their entire lives with another family before being surrendered to a shelter. I’ve never had cats before, growing up we always had dogs, so I don’t really know anything about cats. The thing is, I live alone and work full time, and have been wanting something to come home to for awhile but a dog would be irresponsible of me. After doing a lot of research, I figured two bonded adult cats would be okay alone for ten hours a day.

I found these two and snatched them up within two days of the shelter posting them lol. They are so stunning, and the past 7 weeks has been…. fucking crazy.

I’ve been an anxious mess, just constantly doing research and trying to do everything to the best of my ability. I bought them two cat trees facing windows. They have every type of toy. I went through two different kinds of water fountains before finding one that works. I buy a new wand toy basically once a week. I’m so afraid they’ll be understimulated in my apartment.

So until now, the first cat, Ermy, has been a joy. She plays by herself, is incredibly affectionate, and seems really happy here.

My other cat, Nelly, came home and was immediately extremely affectionate and clingy. The problem is that in the last few weeks, she’s been getting less loving and more… I guess bratty and demanding. When we play together, she seems unimpressed with my wand skills, and just generally seems bored and maybe a little sad. I think ermy picks up on this and tries to engage her in play, but nelly will hiss at her most of the time and go back to staring at me with this frustrated expression. She’s always around me even though she doesn’t snuggle or enjoy pets for more than a minute, but I can’t help but think she’s unhappy about something.

I’m losing my mind because she keeps waking me at 2am for food, and I’m trying so hard to be a good cat mother but it’s so much more stressful than I expected….

Does anyone have any advice for me? I thought about posting this in the cat advice sub, but I rather would talk to people who are familiar with tortitude in case that’s a factor. Maybe this is normal 7 weeks post adoption?

Thanks for reading my vent.
