Thanks!

Just a little update, they're all doing really well now, they all enjoy being picked up and they have begun to jump on my hand rather than me having to catch them. They are pretty wriggly to hold but managable, and they are so lightweight! After I've held one of the gerbils, Tia seems to weigh an awful lot more and she looks huge against them.

They are chewing and digging a lot though, not that we didn't expect that, but I suppose as there's 3 of them everything is 3x what we expected! We've removed several ladders and toys as they've chewed them to almost nothing, and if we give them a kitchen roll to play with, it's shredded completely in the space of 20 minutes. They have a huge wood chew and a special 'chew-tube', but they seem to prefer to chew the things they shouldn't chew We're thinking about getting them a glass or plastic gerbilarium, at the moment they are in Foxy's old cage, which is plenty big enough, but I don't think it's deep enough to satisfy their digging.

Their petsters are up and running too. I plan to take more pics of them in the future, just they aren't the easiest things in the world to take pics of as they never sit still!
