Roxane now grows and is the heaviest of the females at 880 g.
She's gotten to be much less of a biter as she now knows how to use her teeth carefully.
I still haven't had to tell her to use the litterbox. But someone isn't using it all the time. I think Roxane may be blamed for stressing the others and thus partly guilty.
Before she came to us, all others had been using the litterboxes exclusively for two months.
