Cute! One of mine likes to sleep in the same tunnel - she also toilets in it a lot and it's a pain to clean! However, floor time is quite new to them so no time for sleeping during that yet, but as soon as they go back in their pen they all go straight for a nap!
It is a pain to clean isn't it?! I usually just put it on the grass and pour a load of water down it, but I'm sure there must be an easier way!
