males spread their seed whereever and whenever possible (when we haven't snipped their seeds, lol) which is why they have such huge testicles to begin with. field mice are even worse in comparison, and many males die during the time when all the females come into heat at the same time (i'm not sure if this is a species thing or a it's-breeding-season-and-we-have-seasons-because-we-are-not-domesticated thing) cuz they spend so much time trying to mount every female. swamp the field with their genes, so to speak. so i would say that no, rats don't actually form "relationships" with their mates, they just mate because the opposite sex is handy nearby. in the wild, rats kinda just lump together, males and females and whatever, and males mount any female that stays still long enough..
on that note, molly and guppy males (fish, fyi) need 3-4 females each. i had one molly male with one molly female and he chased her all day long and she finally died cuz she didn't have enough time to eat or sleep.
again, no life-partners there, lol.
