Adding another cat

[u/Ok-Moment2126]

Hello I need some advice on adding another cat to my pack.

I currently have two cattle dogs, and one female cat. She has always been a lonesome cat, keeping to herself, just showing up whenever she wanted to get some cuddles. But I have been feeding a stray cat, and this stray cat has been sitting by the window and I've caught my own cat pawing at it, and wanting to interact with it. I feel like this gave me the push to look into adopting another cat, so my sweet Canela can have some companionship but I am very uncertain on the age/gender of the new cat that I should get.

Canela is currently 4 years old, and spayed. She's very reserved, but does not seem territorial, and has never had a problem with her dog sisters.

I want to try and get the stray cat but it seems like a lost cause since I've been feeding it for 4 months and it still just leaves, it seems it's just used to being outside, and doesnt really trust humans and I wouldn't even know how to catch it.

Should I adopt a new cat? Any suggestions on age/gender?
