Does Fluffy need a friend?

I adopted my 3.5 year old cat from a local animal shelter back in February, she adjusted quickly almost like she was my cat her whole life. She’s very social, almost dog-like in that regard, and talkative. A lot of the time I find her meowing when I’m in the shower, or anytime I leave the front room for a bit. But when I leave the house (5 times a week for 8 hours a day) she seems fine, happy to see me, but obviously not in distress that I was gone. But through out the day she’ll go through “meowing episodes” (lasting for a few minutes) that can only be tamed with a kitty toy. She doesn’t necessarily seem depressed, but I can’t help but think she would like a friend. Am I jumping the gun or is Fluffy wanting more company?
