For all the kittens out there who choose to have a partner, it is important to understand what you are seeking and it might also help to know the difference between a dom and a caregiver. You see a dom, more often than not, is more of a sexual partner whereas a caregiver's interest is more directly linked to their partner’s well-being. Both might set rules and routines for a kitten but a doms may be an act of control whilst a caregivers would, more likely, be for the kittens safety.
From what I’ve come to understand, the term caregiver is more often paired with non-sexual kittens, or people who struggle more with completing daily tasks. Caregivers seem to just find joy in the happiness of their pet, and don’t seem to have an overwhelming sexual interest. Although doms (especially ones with master/mistress status) tend to be more sexually invested, and might be the kind of partner to ask for more ‘intimate’ things. This doesn't mean that doms have any less desire to care for their kitten, it simply means there may be a more defined sexual aspect to a relationship.
Now I’m not saying these are the only options when it comes to parters, your significant other(s) might have any mix of these traits or they may have none. It all depends on your own personal situation. But it is also important to be mindful of what you desire, and not allow yourself to get caught up with a partner who doesn't understand or fulfill your needs. I would suggest that you know what kind of relationship you want before you go out and seek it, or at least know whether you seek a sexual relationship or not.
