Just that really - we've had him 4 weeks, so he's now about 5 months old. Seems happy, squeaks alot, eats and drinks well. ..but spends a lot of his time with his tail/rump under the water bottle with the drips making his back wet.
He's not itchy i don't think (seems to clean but not mindless scratching), so assume it's just preference.
It's hot here at the moment but he was born into that and I've been known to have the air con on just for him :-)
Clues?
