Thank goodness Fielding and Bart are staying together, because I can't imagine ever splitting up this pair. These two are tight.
Nearly all the seconds of each day are spent in sync. They're sleeping or sleepy together. They're chasing the same toy, wrestling with the same rug, or getting bathed by the same big cat.
I've even witnessed them using the litter box at the same time. I suppose if you're eating the same food at the same time you very well could poop at the same time!
They are two peas in a pod.
