My youngest cat is a girl and she is very small.
My oldest one is a dude, big
they both were going out to poop, and at some point the youngest one was getting beat up by nextdoor cat, and she started crapping inside..
Put up a litter box and that solved it for her..Neighbour cat went MIA, and another neighbour cat moved in to my place.. so now there is superiority and she poops outside again.
She basically has a body guard, as the Big Ginger likes her a lot.
If anything i think he's slightly friendzoned, he's nice to her and she might from time to time chase him or whack him over the head. women eh..
