Adopting 2 adult cats from different rescues—bad idea?

I am ready to adopt a new cat after my baby passed away in March. I have always only ever had one cat at a time, mostly due to the fact that my last cat hated other cats (which I learned from her reaction to strays she would see through the window), but also because I live in a small space (1 BR apartment).

However I’ve really fallen in love with two sweet girls from different rescues and I’m struggling with deciding which one to adopt. While I wasn’t originally planning on adopting 2 cats, I’m wondering how bad of an idea it would be to get both? They’re obviously not a bonded pair. They are young-ish adults (5 years old and 2 years old). One of them lived with her brother for a while so in theory at least there is some evidence of her getting along with another cat. The other cat doesn’t have any history with other cats so it’s not known how she might get along with them. Especially considering how small my space is, is this a terrible idea? It makes me nervous but I legitimately don’t know how I could say no to either of them 🥺
