Is there a big difference going from 2-3 cats?

I'm not sure where to post this... I'll try here!
We adopted a kitten about a week ago, we believe she's about 8 weeks or so now. The plan is to adopt another one, and a neighbour has 2 kittens that will be ready in another 2 weeks. I think I'm interested in the male, but they also have a female that I found special and I'm thinking about getting both of them... Just wondering how much more it is to go from 2 to 3 cats; I have never had more than one at a time, so going to two is already a step up for me.
Also, since these two kittens are litter mates, how is that going to work out with the female I have already? She is a little bit older than them, by about 2 weeks I think, but I just wonder since she's not their sibling how they will take to each other. All kittens are well socialized and sweet. Especially the one I have already seems very tolerant, doesn't mind car rides etc. and she was in a cage with another kitten (not from same litter) at the shelter.
Thank you for any input you can give me!

Work invloved?
Not really a huge difference.
Vet costs are another matter of course.
We went from 3 to 5, to 4 to 6.
And while there is a very big difference between the commitment of three to the commitment involved with six, the difference between 4 and 6 wasn't that big.

I went from 1 to 2.

Then from 2 to 3.

Then from 3 to 4.

Then, 4 to 6, in one day!

The only thing that's changed in my house is: I have to buy more food, more litter, and of course change the litter box more...

... and, run the vacuum more.

... and, I get a whole lot more leg-rubbings, headbutts, kisses & welcome homes than I did before.

I went from two to three cats earlier this year. It meant adding a litter box, buying more food, higher vet bills, and running the vacum more often, but it's been totally worth it. With yours being so young introductions shouldn't be a problem. Good luck!

Hi, my experience with lots of cats is that a male will eventually try to dominate a female (unless she's a lot older) and it can be pretty stressful for her, if not outright dangerous depending on the cats. Two males will fight, so another female might be the best choice. Spaying/neutering doesn't make a lot of diff. to the above, though should be done regardless for their sakes and your own.

I have to say, my lifetime of experience is just the opposite, all of my males have been much more socialable towards all other cats, my females were the trouble makers, mostly with other females.
Genders matters not, if you're getting kittens of around the same ages, they'll be fine.
Yes, there will be dominance issues until a concrete social order is achieved among them.

Nope, not a big difference in my opinion.

Also in my house: the girls are the little prima dona's.

I think the relationships among the cats get more complex when you go from two to three. In my experience, anyway.

I say I have to agree with Arlyn I went from 2 to 1 to 2 to 3 and my males were more relaxed than the female, she still cause trouble at times
Just a bit more work on my part, more trips to the vet.
But I get 3 times the attention now.

Try telling my males that as they lie together and groom each other and play chase around the house all day
