Long story short (I had the whole story explained...)

I have two pairs of sisters, a rat pair and gerbil pair.

Due to tainted bedding my gerbils got sick, and one died. Meanwhile, my rat sisters are unaware of any loss and continue to squabble.

And so, this is related to that.

And, if anyone's wondering, my remaining gerbil is getting better.
