I have 2 male, Foofy is 6 months and Chewy is 3 months old, they both aren't quiet trained yet. Yes they pee and poop all over the kitchen if i don't let them out on time and i can't tell who did what/when.
But i noticed that Chewy learning is much more accelerated than Foofy b/c he watches what Foofy does then follows.
I love having 2 male...they are so much fun
