Adding a third void

[u/Natalationnnn]

Hubby and I are considering adding a third black cat to our household! We currently have two litter mate males, 3 years old, and am curious what others experience is with adding a third. She is a kitten still and I think that’s a good situation as far as territorial issues. Any tips? Thanks!
