>>81224 (OP)I have a cat.
Males are calmer but pickier about people, and females are more dominant, but you have to play with them more often since they're more active.
Get a single cat AT MOST. If you get a second one there's a chance that they'll hate each other to the point of violence.
As for breeds, it depends on what you want. From my experience fur patterns can also influence personality. You can look that up, but from what I remember white cats are calmer than most but can become deaf (this is a genetic side-effect of all white animals btw) and are more tolerable if you're allergic. Black cats can cause greater allergic reactions, and calicos are the sassy ones. They are extremely active and playful, but do whatever THEY want. They are also the only fur pattern that's not common on males (if it is, it means that the guy can't produce sperm).
<>>81229 is a tard btw. Female cats, neutered or not, WILL drive you insane, especially during winter. Letting them outside is pretty much essential if you want to keep your sanity.
