Boulder loves the bed. When you put him under the covers he does that little "shimmy" move to get down and get comfortable. We do not let him sleep in their all night because he gets scared if something wakes him at night. If he is fast asleep and you touch him he will usually wack his tail once and undulate his body as if threatened for about 10 seconds before he realizes its me and then comes and gives me a lick and crawls into my hands. Any of your Uros do this? It is the only time I have ever seen him wack his tail.
