Well, they don't often stand beside each other very much at the moment - if Ruby comes alongside Charlie it's because she wants to bop him on the ear - or on his tail - so that he will chase her. They spend a lot of time thundering up and down stairs, one chasing after the other.
But they do pause for breath when they get hungry and it's time to eat - so I was able to snatch this photo while things were quiet the other day.
This is as close as they get together when it's food time!
Ruby has grown a lot since she arrived - but she'll have to go a long way to match Charlie!
