There are two litter boxes in back room that they use on a daily basis, they choose either box whichever suits them at the time, they both share the boxes their choice, sometimes both doing their business at the same time ...I kid you not
I'm all for sharing but pooing alongside a partner is a bit much 
Will they eventually decide on a box each and stick to these boxes when their older or is sharing the litter box with sibling a permanent thing?
I suppose I should be grateful their using thelitter box.
